'Undo-ing' changes to Gem source

I was debugging a gem a while ago and accidentally left in some code that causes my project to hang when it makes use of that gem. How can I restore the clean source? Is the only option to uninstall and reinstall?

The command

gem pristine foo

Does this for the gem of that name. You can also pass --all to rebuild all gems. This works by comparing what's in the .gem file (which is a tar archive in disguise) with the actual files. More details in the documentation

Uninstall that gem with gem uninstall <gem_name> and then reinstall via gem install <gem_name> or bundle install.
