eval service fails to build

[Lyannen258]

In a newly cloned repository, docker-compose up does not work, because the eval service fails to build.

Your bundle is locked to mimemagic (0.3.3), but that version could not be found
in any of the sources listed in your Gemfile. If you haven't changed sources,
that means the author of mimemagic (0.3.3) has removed it. You'll need to update
your bundle to a version other than mimemagic (0.3.3) that hasn't been removed
in order to install.
The command '/bin/sh -c bundle install --jobs 20 --retry 5 && gem install bundler' returned a non-zero code: 7
ERROR: Service 'eval' failed to build : Build failed

Simple workaround is to just comment out the eval service in docker-compose.yml, if it is not needed.

This issue probably has the solution.
