I'm using Travis CI for a rails project, and I'm getting a "Could not find foobar-0.2.3 gem in any of the sources." at the bundle install
stage. (sorry, not at my computer right now, and don't remember the exact gem)
It looks like this is because a new version of that gem was recently put on RubyGems, and the old version of the gem (which is in my Gemfile.lock) was yanked.
How am I supposed to fix this break? Am I supposed to manually go into my Gemfile.lock and put the correct version? (Manually editing the Gemfile.lock seems weird to me, not sure if that's what you're supposed to do.)
