Ruby Language Server is trying to load gems from a different ruby

[eirvandelden]

What I did

• Install 2 rubies with ruby-install, switch between them with chruby.
  • Let's assume Ruby 3.0.2 is the default, and a project requires 2.7.5
• Start Nova from iTerm in a rails project (running on ruby 2.7.5) with nova . (I don't know if this step matters)

What I expected

• No warnings in the Extension Console

What I got

Ruby Language Server[11:21:37.494000] [WARN] Warning: the running version of Bundler (2.2.22) is older than the version that created the lockfile (2.3.7). We suggest you to upgrade to the version that created the lockfile by running `gem install bundler:2.3.7`.

Observations

Looking at the warning log, whatever is used for the Ruby Language Server (I guess that will be solar graph?) is being run in the wrong context. It is missing gems, because it is looking for them in my default ruby. But this project is running in a different ruby (2.7.5).

With PR #17 up, I found out why I'm getting an error in #15:

This is the same issue as above: my default ruby is 3.0.2, but the project is a different ruby version. The new processes that are spawned are run against the default ruby, not those defined in the project itself.

For the record, I'm using postmodern's chruby which uses bash to change ruby versions based on a .ruby-version file.
