Gitpod: Can't find rubocop command

[shafy]

Your environment

• vscode-ruby version: 0.27.0
• Ruby version: 3.0.0
• Ruby version manager (if any): RVM
• VS Code version: 1.58.2
• Operating System: Gitpod (I think Linux)
• Using language server? (eg useLanguageServer is true in your configuration?) Yes

Expected behavior

I expect VS Code to find rubocop as it is installed as a gem and is accessible from the terminal.

Actual behavior

This issue is probably specific to Gitpod and I have found a solution that feels hacky. So I would like to discuss it here and see if I'm missing something. When I install Ruby with the following Dockerfile, rubocop is accessible from the terminal but VS Code can't find the command:

FROM gitpod/workspace-postgres
USER gitpod

# Install the Ruby version specified in '.ruby-version'
COPY --chown=gitpod:gitpod .ruby-version /tmp
RUN echo "rvm_gems_path=/home/gitpod/.rvm" > ~/.rvmrc
RUN bash -lc "rvm reinstall ruby-$(cat /tmp/.ruby-version) && rvm use ruby-$(cat /tmp/.ruby-version) --default && gem install rails"
RUN echo "rvm_gems_path=/workspace/.rvm" > ~/.rvmrc

I get the following error in the Language Server Output:

Lint: executing rubocop -s '/workspace/fugu/app/controllers/projects_controller.rb' -f json -R -l...

Lint: unable to execute rubocop -s '/workspace/fugu/app/controllers/projects_controller.rb' -f json -R -l as the command could not be found

SIGPIPE received

which ruby returns this:

/home/gitpod/.rvm/rubies/ruby-3.0.0/bin/ruby

which rubocop returns this:

/workspace/.rvm/ruby-3.0.0/bin/rubocop

Both paths are in my $PATH variable.

If I install the rubocop gems like this in the Dockerfile, it works:

FROM gitpod/workspace-postgres
USER gitpod

# Install the Ruby version specified in '.ruby-version'
COPY --chown=gitpod:gitpod .ruby-version /tmp
RUN echo "rvm_gems_path=/home/gitpod/.rvm" > ~/.rvmrc
RUN bash -lc "rvm reinstall ruby-$(cat /tmp/.ruby-version) && rvm use ruby-$(cat /tmp/.ruby-version) --default && gem install rails rubocop rubocop-performance rubocop-rails rubocop-rspec"
RUN echo "rvm_gems_path=/workspace/.rvm" > ~/.rvmrc

You can find my repo here run it directly in Gitpod here (you need a free Gitpod account).

Is this expected behavior or some bug?

Can you increase your log level in settings to see more details on what is being run? That does look like it isn't detecting the RVM environment correctly.

Hey @wingrunr21 yes it looks like it doesn't detect the RVM environment, and I think it's a specific issue to how Gitpod sets up the environment. I'll try to increase the log level and see if it helps. I'm travelling currently and will only get to it in about two weeks, just fyi.
