Uninstall all installed gems, in OSX?
ruby, rubygems
Solution
You could also build out a new Gemfile and run `bundle clean --force`. This will remove all other gems that aren't included in the new Gemfile.
Problem
There are instances where I would like to revert and uninstall all previous gem installations. For instance, I needed to assist a friend migrate their rails development machine to use RVM. As they had been previously using the system-wide `gem`, he was experiencing many headaches when working with multiple projects. Essentially, he was the poster-child for an RVM convert. How can I elegantly uninstall all of the gems on his OSX system?
