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.

# File bundler/lazy_specification.rb, line 55
def satisfies?(dependency)
  effective_requirement = dependency.requirement == Gem::Requirement.default ? Gem::Requirement.new(">= 0.A") : dependency.requirement

  @name == dependency.name && effective_requirement.satisfied_by?(Gem::Version.new(@version))
