This document describes how I set up my developer environment on a new MacBook or iMac. We will set up Python, Node (JavaScript), and Ruby environments, mainly for JavaScript development. Even if you don't program in all three, it is good to have them as many command-line tools use one of them. As you read and follow these steps, feel free to send me any feedback or comments you may have.
The document assumes you are new to Mac. The steps below were tested on OS X Mountain Lion.
- System update
- System preferences
- Google Chrome
- iTerm2
- Homebrew
- Beautiful terminal
- Dotfile source control

First thing you need to do, on any OS acutally, is update the system! For that: Apple Icon > Software Update...
If this is a new computer, there are a couple tweaks I like to make to the System Preferences. Feel free to follow these, or to ignore them, depending on your personal preferences.
In Apple Icon > System Preferences:
- Trackpad > Tap to click
- Keyboard > Key Repeat > Fast (all the way to the right)
- Keyboard > Delay Until Repeat > Short (all the way to the right)
- Dock > Automatically hide and show the Dock
Install your favorite browser, mine happens to be Chrome.
Download from www.google.com/chrome. Open the .dmg file once it's done downloading (this will mount the disk image), and drag and drop the Google Chrome app into the Applications folder (on the Mac, most applications are installed this way). When done, you can unmount the disk in Finder (the small "eject" icon next to the disk under Devices).
Since we're going to be spending a lot of time in the command-line, let's install a better terminal than the default one. Download and install iTerm2 (the newest version, even if it says "beta release").
In Finder, drag and drop the iTerm Application file into the Applications folder.
You can now launch iTerm, through the Launchpad for instance.
Let's just quickly change some preferences. In iTerm > Preferences..., under the tab General, uncheck Confirm closing multiple sessions and Confirm "Quit iTerm2 (Cmd+Q)" command under the section Closing.
In the tab Profiles, create a new one with the "+" icon, and rename it to your first name for example. Then, select Other Actions... > Set as Default. Finally, under the section Window, change the size to something better, like Columns: 125 and Rows: 35.
When done, hit the red "X" in the upper left (saving is automatic in OS X preference panes). Close the window and open a new one to see the size change.
Package managers make it so much easier to install and update applications (for Operating Systems) or libraries (for programming languages). The most popular one for OS X is Homebrew.
In the terminal paste the following line
(without the $), hit Enter, and follow the steps on the screen:
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
You'll be prompted to install Command Line Tools for Xcode. When the installation of Command Line Tools is complete, Homebrew will continue installing.
One thing we need to do is tell the system to use programs installed by Homebrew (in /usr/local/bin) rather than the OS default if it exists. We do this by adding /usr/local/bin to your $PATH environment variable:
$ echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile
Open an new terminal tab with Cmd+T (you should also close the old one), then run the following command to make sure everything works:
$ brew doctor
To install a package (or Formula in Homebrew vocabulary) simply type:
$ brew install <formula>
To update Homebrew's directory of formulae, run:
$ brew update
Note: I've seen that command fail sometimes because of a bug. If that ever happens, run the following (when you have Git installed):
$ cd /usr/local
$ git fetch origin
$ git reset --hard origin/master
To see if any of your packages need to be updated:
$ brew outdated
To update a package:
$ brew upgrade <formula>
Homebrew keeps older versions of packages installed, in case you want to roll back. That rarely is necessary, so you can do some cleanup to get rid of those old versions:
$ brew cleanup
To see what you have installed (with their version numbers):
$ brew list --versions
$ brew install bash-completion
Since we spend so much time in the terminal, we should try to make it a more pleasant and colorful place. What follows might seem like a lot of work, but trust me, it'll make the development experience so much better.
Let's go ahead and start by changing the font. In iTerm > Preferences..., under the tab Profiles, section Text, change both fonts to Consolas 13pt.
(Note: you may have to install Consolas, instructions for doing so can be found here)
Now let's add some color. I'm a big fan of the Solarized color scheme. It is supposed to be scientifically optimal for the eyes. I just find it pretty.
Scroll down the page and download the latest version. Unzip the archive. In it you will find the iterm2-colors-solarized folder with a README.md file, but I will just walk you through it here:
- In iTerm2 Preferences, under Profiles and Colors, go to Load Presets... > Import..., find and open the two .itermcolors files we downloaded.
- Go back to Load Presets... and select Solarized Dark to activate it. Voila!
Note: You don't have to do this, but there is one color in the Solarized Dark preset I don't agree with, which is Bright Black. You'll notice it's too close to Black. So I change it to be the same as Bright Yellow, i.e. R 83 G 104 B 112. Skip this step if installing Solarized for Vim as it will make the background too bright for the text.
Not a lot of colors yet. We need to tweak a little bit our Unix user's profile for that. This is done (on OS X and Linux), in the ~/.bash_profile text file (~ stands for the user's home directory).
We'll come back to the details of that later, but for now, just download the files .bash_profile, .bash_prompt, .aliases attached to this document into your home directory (.bash_profile is the one that gets loaded, I've set it up to call the others):
$ cd ~
$ curl -O https://raw.github.com/jkatsnelson/mac-dev-setup-js/master/.bash_profile
$ curl -O https://raw.github.com/jkatsnelson/mac-dev-setup-js/master/.bash_prompt
$ curl -O https://raw.github.com/jkatsnelson/mac-dev-setup-js/master/.aliases
With that, open a new terminal tab (Cmd+T) and see the change! Try the list commands: ls, ls -lh (aliased to ll), ls -lha (aliased to la).
At this point you can also change your computer's name, which shows up in this terminal prompt. If you want to do so, go to System Preferences > Sharing. For example, I changed mine from "Nicolas's MacBook Air" to just "MacBook Air", so it shows up as MacBook-Air in the terminal.
Now we have a terminal we can work with!
To enable whole-word skipping while holding down alt plus the left or right arrow keys, Go to iTerm preferences > Profiles and choose your user profile. Then select the 'Keys' tab.
Add the following two shortcuts:
Keyboard Shortcut: alt + left arrow
Action: send escape sequence
Enter the letter 'b' in the text field next to 'Esc +'
Keyboard Shortcut: alt + right arrow
Action: send escape sequence
Enter 'f' in the text field next to 'Esc +'
-run this command in your terminal to make unix auto-completion case-insensitive
$ echo "set completion-ignore-case On" >> ~/.inputrc
(Thanks to Mathias Bynens for his awesome dotfiles.)
It is recommended that you place your workstation configuration dotfiles under source control, as explained here (ignore the 'Setting up a new Mac section').
What's a developer without Git? To install, simply run:
$ brew install git
When done, to test that it installed fine you can run:
$ git --version
And $ which git should output /usr/local/bin/git.
Let's set up some basic configuration. Download the .gitconfig file to your home directory:
$ cd ~
$ curl -O https://raw.github.com/nicolahery/mac-dev-setup/master/.gitconfig
It will add some color to the status, branch, and diff Git commands, as well as a couple aliases. Feel free to take a look at the contents of the file, and add to it to your liking.
Next, we'll define your Git user (should be the same name and email you use for GitHub and Heroku):
$ git config --global user.name "Your Name Here"
$ git config --global user.email "your_email@youremail.com"
They will get added to your .gitconfig file.
To push code to your GitHub repositories, we're going to use the recommended HTTPS method (versus SSH). So you don't have to type your username and password everytime, let's enable Git password caching as described here:
$ git config --global credential.helper osxkeychain
Note: On a Mac, it is important to remember to add .DS_Store (a hidden OS X system file that's put in folders) to your .gitignore files. You can take a look at this repository's .gitignore file for inspiration.
With the terminal, the text editor is a developer's most important tool. Everyone has their preferences, but unless you're a hardcore Vim user, a lot of people are going to tell you that Sublime Text is currently the best one out there.
Go ahead and download it. Open the .dmg file, drag-and-drop in the Applications folder, you know the drill now. Launch the application.
Note: At this point I'm going to create a shorcut on the OS X Dock for both for Sublime Text and iTerm. To do so, right-click on the running application and select Options > Keep in Dock.
Sublime Text is not free, but I think it has an unlimited "evaluation period". Anyhow, we're going to be using it so much that even the seemingly expensive $60 price tag is worth every penny. If you can afford it, I suggest you support this awesome tool. :)
Just like the terminal, let's configure our editor a little. Go to Sublime Text 2 > Preferences > Settings - User and paste the following in the file that just opened:
{
"font_face": "Consolas",
"font_size": 13,
"rulers":
[
79
],
"highlight_line": true,
"bold_folder_labels": true,
"highlight_modified_tabs": true,
"tab_size": 2,
"translate_tabs_to_spaces": true,
"word_wrap": false,
"indent_to_bracket": true
}Feel free to tweak these to your preference. When done, save the file and close it.
I use tab size 2 for everything except Python and Markdown files, where I use tab size 4. If you have a Python and Markdown file handy (or create dummy ones with $ touch dummy.py), for each one, open it and go to Sublime Text 2 > Preferences > Settings - More > Syntax Specific - User to paste in:
{
"tab_size": 4
}Now for the color. I'm going to change two things: the Theme (which is how the tabs, the file explorer on the left, etc. look) and the Color Scheme (the colors of the code). Again, feel free to pick different ones, or stick with the default.
A popular Theme is the Soda Theme. To install it, run:
$ cd ~/Library/Application\ Support/Sublime\ Text\ 2/Packages/
$ git clone https://github.com/buymeasoda/soda-theme/ "Theme - Soda"
Then go to Sublime Text 2 > Preferences > Settings - User and add the following two lines:
"theme": "Soda Dark.sublime-theme",
"soda_classic_tabs": true
Restart Sublime Text for all changes to take affect (Note: on the Mac, closing all windows doesn't close the application, you need to hit Cmd+Q).
The Soda Theme page also offers some extra color schemes you can download and try. But to be consistent with my terminal, I like to use the Solarized Color Scheme, which already ships with Sublime Text. To use it, just go to Sublime Text 2 > Preferences > Color Scheme > Solarized (Dark). Again, this is really according to personal flavors, so pick what you want.
Sublime Text 2 already supports syntax highlighting for a lot of languages. I'm going to install a couple that are missing:
$ cd ~/Library/Application\ Support/Sublime\ Text\ 2/Packages/
$ git clone https://github.com/jashkenas/coffee-script-tmbundle CoffeeScript
$ git clone https://github.com/miksago/jade-tmbundle Jade
$ git clone https://github.com/danro/LESS-sublime.git LESS
$ git clone -b SublimeText2 https://github.com/kuroir/SCSS.tmbundle.git SCSS
$ git clone https://github.com/nrw/sublime-text-handlebars Handlebars
Let's create a shortcut so we can launch Sublime Text from the command-line:
$ cd ~
$ mkdir bin
$ ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/bin/subl
Now I can open a file with $ subl myfile.py or start a new project in the current directory with $ subl .. Pretty cool. (Note: the path to the apps shared support folder will change depending on the version of sublime.)
Install the Sublime Package Control.
To install individual packages, bring up the Command Palette with Cmd+Shift+P and type "install." Select "Package Control: Install Package." Once the repositories load search for and install the following packages:
- Dust
- Sass
- Chai completions
- Chef
- CoffeeLinter
- Backbone
- Backbone Marionette
- Color Highlighter
- Emmet
- Sublime Linter
- Plain Tasks
It's recommended to style PlainTasks to something more palatable than the default yellow sticky color.
Download the following Plain Tasks theme here and add it to the folder ~/Library/Application Support/Sublime Text 2/Packages/PlainTasks
Navigate to Preferences -> Package Settings -> Plain Tasks -> Settings - User and update the config file to contain:
{
...
"color_scheme": "Packages/PlainTasks/DarkNotes.tmTheme"
...
}
OS X, like Linux, ships with Python already installed. But you don't want to mess with the system Python (some system tools rely on it, etc.), so we'll install our own version with Homebrew. It will also allow us to get the very latest version of Python 2.7.
The following command will install Python 2.7 and any dependencies required (it can take a few minutes to build everything):
$ brew install python
When finished, you should get a summary in the terminal. Running $ which python should output /usr/local/bin/python.
It also installed Pip (and its dependency Distribute), which is the package manager for Python. Let's upgrade them both:
$ pip install --upgrade setuptools
$ pip install --upgrade distribute
$ pip install --upgrade pip
Executable scripts from Python packages you install will be put in /usr/local/share/python, so let's add it to the $PATH. To do so, we'll create a .path text file in the home directory (I've already set up .bash_profile to call this file):
$ cd ~
$ subl .path
And add these lines to .path:
PATH=/usr/local/share/python:$PATH
export PATHSave the file and open a new terminal to take the new $PATH into account (everytime you open a terminal, .bash_profile gets loaded).
Here are a couple Pip commands to get you started. To install a Python package:
$ pip install <package>
To upgrade a package:
$ pip install --upgrade <package>
To see what's installed:
$ pip freeze
To uninstall a package:
$ pip uninstall <package>
Node Version Manager (NVM)
Simple bash script to manage multiple active node.js versions
If you have git installed, then just clone the repo (More info here: https://github.com/creationix/nvm#manual-install:
git clone https://github.com/creationix/nvm.git ~/.nvm
To activate nvm, you need to source it from your bash shell
source ~/.nvm/nvm.sh
I always add this line to my ~/.bashrc or ~/.profile file (you may need to add this line to ~/.bash_profile file instead) to have it automatically sourced upon login. Often I also put in a line to use a specific version of node.
Use nvm to install the latest version of node
nvm install 0.10
Node modules are installed locally in the node_modules folder of each project by default, but there are at least a few that are worth installing globally. Those are CoffeeScript, Grunt, Bower, and Yeoman:
$ npm install -g coffee-script
$ npm install -g grunt-cli
$ npm install -g bower
$ npm install -g yo
To install a package:
$ npm install <package> # Install locally
$ npm install -g <package> # Install globally
To install a package and save it in your project's package.json file:
$ npm install <package> --save
To see what's installed:
$ npm list # Local
$ npm list -g # Global
To find outdated packages (locally or globally):
$ npm outdated [-g]
To upgrade all or a particular package:
$ npm update [<package>]
To uninstall a package:
$ npm uninstall <package>
Like Python, Ruby is already installed on Unix systems. But we don't want to mess around with that installation. More importantly, we want to be able to use the latest version of Ruby.
When installing Ruby, best practice is to use rbenv (Ruby Version Manager) which allows you to manage multiple versions of Ruby on the same machine. Follow the steps here to checkout and install rbenv. Also, install the rbenv-gem-rehash plugin.
Compatibility note: rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv.
You are encouraged to install ruby-build using brew install ruby-build for managing the installation of new versions of ruby. Using ruby-build and bash-completion, installing a version of Ruby is as easy as typing rbenv install, then pressing tab twice to get a list of all available versions.
For example, install the latest version of 2.0.X:
$ rbenv install 2.0.X-pXXX
To use this version globally now run..
$ rbenv global 2.0.X-pXXX
RubyGems, the Ruby package manager, was also installed:
$ which gem
Update to its latest version with:
$ gem update --system
To install a "gem" (Ruby package), run:
$ gem install <gemname>
To install without generating the documentation for each gem (faster):
$ gem install <gemname> --no-rdoc --no-ri
To see what gems you have installed:
$ gem list
To check if any installed gems are outdated:
$ gem outdated
To update all gems or a particular gem:
$ gem update [<gemname>]
RubyGems keeps old versions of gems, so feel free to do come cleaning after updating:
$ gem cleanup
I mainly use Ruby for the CSS pre-processor Compass, which is built on top of Sass:
$ gem install compass --no-rdoc --no-ri
$ gem install bundler --no-rdoc --no-ri
$ gem install compass --no-rdoc --no-ri
$ gem install berkshelf --no-rdoc --no-ri
$ gem install chef --no-rdoc --no-ri
Never run rbenv rehash again. This rbenv plugin automatically runs rbenv rehash every time you install or uninstall a gem. Make sure you have rbenv 0.4.0 or later, then run:
$ git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash
More details here.
Heroku, if you're not already familiar with it, is a Platform-as-a-Service (PaaS) that makes it really easy to deploy your apps online. There are other similar solutions out there, but Heroku was among the first and is currently the most popular. Not only does it make a developer's life easier, but I find that having Heroku deployment in mind when building an app forces you to follow modern app development best practices.
Assuming that you have an account (sign up if you don't), let's install the Heroku Client for the command-line. Heroku offers a Mac OS X installer, the Heroku Toolbelt, that includes the client. But for these kind of tools, I prefer using Homebrew. It allows us to keep better track of what we have installed. Luckily for us, Homebrew includes a heroku-toolbelt formula:
$ brew install heroku-toolbelt
The formula might not have the latest version of the Heroku Client, which is updated pretty often. Let's update it now:
$ heroku update
Don't be afraid to run heroku update every now and then to always have the most recent version.
Login to your Heroku account using your email and password:
$ heroku login
If this is a new account, and since you don't already have a public SSH key in your ~/.ssh directory, it will offer to create one for you. Say yes! It will also upload the key to your Heroku account, which will allow you to deploy apps from this computer.
If it didn't offer create the SSH key for you (i.e. your Heroku account already has SSH keys associated with it), you can do so manually by running:
$ mkdir ~/.ssh
$ ssh-keygen -t rsa
Keep the default file name and skip the passphrase by just hitting Enter both times. Then, add the key to your Heroku account:
$ heroku keys:add
Once the key business is done, you're ready to deploy apps! Heroku has a great Getting Started guide, so I'll let you refer to that (the one linked here is for Python, but there is one for every popular language). Heroku uses Git to push code for deployment, so make sure your app is under Git version control. A quick cheat sheet (if you've used Heroku before):
$ cd myapp/
$ heroku create myapp
$ git push heroku master
$ heroku ps
$ heroku logs -t
The Heroku Dev Center is full of great resources, so be sure to check it out!
This really depends on how you want to organize your files, but I like to put all my version-controlled projects in ~/Projects. Other documents I may have, or things not yet under version control, I like to put in ~/Code.
Vagrant is open-source software for creating and configuring virtual development environments. It can be considered a wrapper around VirtualBox and configuration management software such as Chef, Salt and Puppet.
Download the latest stable version (v1.3.5), open the installer and follow the instructions.
Oracle VM Virtual Box is a virtualization tool that allows you to create virtual machines on Mac OS X, Linux, or Windows.
Download and start the installer and follow the instructions.
Go to the Adobe Creative Cloud site and set up an account. You'll download the creative cloud app which will allow you to download 30 day trial versions of any application you may need. Monsoon can provide licenses as needed when the trial version of the application has expired.
Other apps to download:
- Slack Group chat and IM for teams.
- Yeoman: Follow the download instructions. You should already have grunt, but you want yeoman and bower too.
- Dropbox: Design shares assets and wireframes and comps with us through Dropbox. You need a dropbox account with your work email.
- Google Drive: File syncing to the cloud too! I use Google Docs a lot to collaborate with others (edit a document with multiple people in real-time!), and sometimes upload other non-Google documents (pictures, etc.), so the app comes in handy for that. (Free for 5GB)
- Dillinger: Dillinger is a free, open source markdown editor in the browser. Use the hosted app or download it yourself.
- Spaces: Multiple desktop feature. Support page for OS X 10.6 here
- Alfred: Application hot-launching. Open with Option + Space and start typing what you're looking for. Does lots of other cool stuff.
- SizeUp: A window management tool. Maps shortcuts that arrange your windows into neat little halves/quadrants/etc. It's a paid app with an unlimited trial period, the caveat being that it will bug you with a "Buy a license prompt" every so often.
