    #ruby_platform_materializes_to_ruby_platform?  ⇒ Boolean  (readonly, private)
  



  

    

For backwards compatibility with existing lockfiles, if the most specific locked platform is not a specific platform like x86_64-linux or universal-java-11, then we keep the previous behaviour of resolving the best platform variant at materiliazation time. For previous bundler versions (before 2.2.0) this was always the case (except when the lockfile only included non-ruby platforms), but we’re also keeping this behaviour on newer bundlers unless users generate the lockfile from scratch or explicitly add a more specific platform.

    #__materialize__(candidates, fallback_to_non_installable: Bundler.frozen_bundle?)  
  



  

    

If in frozen mode, we fallback to a non-installable candidate because by doing this we avoid re-resolving and potentially end up changing the lock file, which is not allowed. In that case, we will give a proper error about the mismatch higher up the stack, right before trying to install the bad gem.

    #satisfies?(dependency)  ⇒ Boolean 
  



  

    

Does this locked specification satisfy dependency?



NOTE: Rubygems default requirement is “>= 0”, which doesn’t match prereleases of 0 versions, like “0.0.0.dev” or “0.0.0.SNAPSHOT”. However, bundler users expect those to work. We need to make sure that Gemfile dependencies without explicit requirements (which use “>= 0” under the hood by default) are still valid for locked specs using this kind of versions. The method implements an ad-hoc fix for that. A better solution might be to change default rubygems requirement of dependencies to be “>= 0.A” but that’s a major refactoring likely to break things. Hopefully we can attempt it in the future.
