Results logged to /srv/errbit/git-errbit/.bundle/ruby/2.5.0/extensions/x86_64-linux/2.5.0/libv8-3.16.14.19/gem_make.out

An error occurred while installing libv8 (3.16.14.19), and Bundler cannot continue.
Make sure that `gem install libv8 -v '3.16.14.19' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  therubyracer was resolved to 0.12.3, which depends on
    libv8

I have tried installing therubyracer and libv8 with local install etc.

gem install --no-user-install --install-dir /srv/errbit/git-errbit/.bundle/ruby/2.5.0/gems libv8 -v '3.16.14.19' -- --use-system-libraries
which completes successfully, but seems not to help as after a new bundle install libv8 gets installed again and fails.

Steps to reproduce:

1. Use Arch Linux
2. Install Ruby and rubygems from arch/aur (depends on version)
3. clone errbit
4. run bundle install

I have no arch to test but you can set flags for bundle to use while building. Maybe one of these two can help you?

bundle config set build.libv8 --use-system-libraries
or
bundle config set build.libv8 --with-system-v8

and then bundle. Note those config settings are global for your user an are saved in ~/.bundle/config as opposed to <project>/.bundle/config

That's a good tip, thanks, as this helped to install libv8 gem with bundler.

But now therubyracer fails.
I have tried with v8, v8-3.14 and v8-r from AUR, none of them are working. Not sure if they are correct v8 libraries, though.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

of V8 found on your system and *not* the one that is bundled with
the libv8 rubygem.

However, your system version of v8 could not be located.

Please make sure your system version of v8 that is compatible
with 3.16.14.19 installed. You may need to use the
--with-v8-dir option if it is installed in a non-standard location

I'm having the same issue when deploying to Heroku.

I guess you don't get updates for issue mentions so if you haven't found a solution yet and are still interested I outlined a solution that potentially also fixes your issue. I might have some time in the coming days to make this solution a PR but for the meantime... #1494 (comment)
