# 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.

# on newer bundlers unless users generate the lockfile from scratch or
