Fails to install gem if it has prerelease gems in its dependencies.

[shkrt]

For example:

$ gem specific_install 'rails/rails'

or

$ gem specific_install 'https://github.com/rails/rails.git'

or

$ gem specific_install -l 'https://github.com/rails/rails.git'

results in:

$ ERROR:  While executing gem ... (Gem::UnsatisfiableDependencyError)
    Unable to resolve dependency: 'rails (= 5.2.0.alpha)' requires 'railties (= 5.2.0.alpha)'

and if we start to install dependencies one-by-one, we also got stuck:

$ gem specific_install 'https://github.com/rails/rails.git' -d activesupport`  # -Success
$ gem list activesupport 
$ activesupport (5.2.0.alpha, 5.1.4)
$ gem specific_install 'https://github.com/rails/rails.git' -d actionview
$ ERROR:  While executing gem ... (Gem::DependencyError)
    Unresolved dependency found during sorting - activesupport (>= 4.2.0) (requested by rails-dom-testing-2.0.3)

This is caused by the presence of prerelease gems in gem's dependencies. If we initialize Gem::DependencyInstaller with prerelease:true, then at least gem specific_install 'rails/rails' -d actionview seems to work fine. So, I think it would be convenient to add some command line flag, that will set prerelease option to true, if provided.

Can you think of an easy way to fix this command line wise?

Will think of solving it, but I've yet to figure out the case with nested prerelease dependencies, because with Gem::DependencyInstaller.new(prerelease: true).install dep_name we can install 'rails/rails' repository step-by-step:

$ gem specific_install 'https://github.com/rails/rails.git' -d actionview

but the following

$ gem specific_install 'rails/rails'

keeps failing

I'm not sure if rubygems has a way to do dependencies while building a local gem unfortunately...
