Windows installation issue - incompatible Ruby dependencies

[KevinBuchs]

Version:

~> 3.0

Environment:

Windows Server 2019

Scenario:

I'm getting complaints from Ruby bundler upon installing mixlib-shellout.

Steps to Reproduce:

Install Ruby 2.7.1, Bundler
bundle config --local set specific_platform true

In gemspec:

 if specification.platform == 'x64_mingw'
    default_platform = specification.platform
    specification.platform = 'universal_mingw'
    specification.add_runtime_dependency "mixlib-shellout", "~> 3.0"
    specification.platform = default_platform
  else
    specification.add_runtime_dependency "mixlib-shellout", "~> 3.0"
  end

bundle install

Expected Result:

Happy Install

Actual Result:

Error message:
Unable to use the platform-specific (universal-mingw32) version of mixlib-shellout (3.1.4) because it has different dependencies from the ruby version. To use the platform-specific version of the gem, run `bundle config set specific_platform true` and install again.

I have been trying to work around this one for a few days now. As you can see, I tried the recommended action. I also tried to work the gemspec so the platform would be happy. I'm beginning to wonder if this gem just does not work with Ruby 2.7.1

hmm. a bundle install in master on ruby 2.7.1 works for me on windows. I wonder if this at all related to the gem that is adding it as a dep.

Well, it is a primary gem, used by the application. (Probably wrong terminology, no Ruby expert here). The Gemspec is referenced by the bundle install. For context, here is the full Gemspec:

# frozen_string_literal: true

  $LOAD_PATH.include? directory or $LOAD_PATH.unshift directory

Now that I see this is kitchen-terraform, I cloned that repo and copied in this gemspec. I did have to comment out mini_racer because it couldn't build libv8 due to some syntax error/python. I also commented out reek which was causing:

Bundler found conflicting requirements for the Ruby version:
  In gems.rb:
    Ruby (~> 2.7)

    reek (~> 5.5) was resolved to 5.6.0, which depends on
      psych (~> 3.1.0) was resolved to 3.1.0, which depends on
        Ruby (< 2.6, >= 2.3) x64-mingw32

However after commenting those 2 gems, my bundle install with ruby 2.7.1 worked. I wonder if you could try deleting your gems.locked file and try installing again.

Thanks, Matt. Problem is solved.
