Please make #783 Optional

[aservedio-swi]

Ensure the following before filing this issue

• I verified it reproduces with the latest version with - uses: ruby/setup-ruby@v1 (see Versioning policy)

• I tried to reproduce the issue locally by following the workflow steps (including all commands done by ruby/setup-ruby, except for Downloading Ruby & Extracting Ruby),
  and it did not reproduce locally (if it does reproduce locally, it's not a ruby/setup-ruby issue)

Are you running on a GitHub-hosted runner or a self-hosted runner?

self-hosted runner

Link to the failed workflow job (must be a public workflow job, so the necessary information is available)

Will copy in step that failed

Any other notes?

For our self-hosted runners, #783 is failing as it is not finding (most likely does not have permission to run) cat <- clearly wrong as I did not read the error message carefully enough - it was a null lockfile.

Can this feature be made optional?

The action was configured as:

 - name: Set up Ruby 2.7
 uses: ruby/setup-ruby@v1
 with:
 # Not needed with a .ruby-version file
 ruby-version: 2.7.6
 # The version of RubyGems to use. Either 'default' (the default), 'latest', or a version number (e.g., 3.3.5).
 rubygems: 3.2.3
 # runs 'bundle install' and caches installed gems automatically
 bundler-cache: true

Output:

I reverted that change for now in #789.

So I think that means you use bundler-cache: true but you don't have a Gemfile?
That's a bit of a weird case, but since it worked before yes it makes sense to not break it:

setup-ruby/bundler.js

Line 151 in 0ecad18

console.log('Could not determine gemfile path, skipping "bundle install" and caching')
