mkdirp@0.5.1 is no longer supported...

[metaverde]

First, I super-appreciate the Truffle team and Truffle.
Thank-you for all you do.

I apologize if this has already been raised.
I scrolled around and did not see it.

• [X ] I've asked for help in the Truffle Gitter before filing this issue.

Yes. Additionally the same issue was raised earlier and not addressed.
It is also an issue with netlify/cli as well as some other repositories.

Issue

I get this warning when I install Truffle using the npm install -g truffle command:

npm WARN deprecated mkdirp@0.5.1: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

Steps to Reproduce

All I have to do to get this is to install Truffle.

Expected Behavior

I would expect at the least to be able to find how to update/upgrade to the proper mkdirp.
I realize this is not the fault of the Truffle team in any way.

Actual Results

I google and search and cannot find how to update/upgrade/install new mkdirp.
I have not yet used the Truffle to see if there are issues with it.
The warning says the API surface has changed to use Promises in 1.x., so I anticipate there will be issues?

Environment

• Operating System: Ubuntu 18.04, aws ec2 instance
• Ethereum client: not yet installed
• Truffle version (truffle version): 5.1.22
• node version (node --version): v10.20.1
• npm version (npm --version): 6.14.4

Thanks @metaverde for bringing this up! It would be good to see if we can bump this.

@metaverde In the last version of Truffle (5.1.23) mkdir was removed. Happy day! Thanks again for creating the issue.

But when I install Truffle occur same problem

npm install truffle -g

@fudingyu If you run npm uninstall -g truffle && npm install -g truffle do you still see that error?

I've tried replicating the error on node versions v8.x, v10.x, & v12.x, but have not seen that deprecation message.

Thanks for sharing that @fudingyu !

Looks like mocha, one of truffle's external dependencies, is puling in this older version of mkdirp.

Got the same issue here. clean install under a fresh windows 10 machine

C:\Windows\System32>truffle version
Truffle v5.1.33 (core: 5.1.33)
Solidity v0.5.16 (solc-js)
Node v14.5.0
Web3.js v1.2.1

I think it is a warning from a dependency that has mkdirp as a dependency. I'm not sure we can do much about that I guess :)

Update: Oops I see that Cruz already mentioned this. I think we have an effort right now going on to update Mocha.

[eggplantzzz]

I'm going to close this for maintenance. Truffle has removed mkdirp as a direct dependency which is about as much as we can do for now. Eventually I suppose some of Truffle's dependencies will get off of mkdirp as well. Thanks everyone!

@metaverde @fudingyu @Peter197903 This should have been resolved by #3146 . The next official release should be out later today, but if you'd like to test this ASAP, feel free to give npm i truffle@next a shot.
