How to delete project ROR

Just delete the complete folder (project in the example you showed).


One caveat: if you installed gems into an external gemset, those will
hang around. A couple alternative:

- Put them in a project-specific rvm gemset when starting the project,
then delete that too when you want to delete the alternative. If you
feel like manipulating your gem path manually (or via other tools),
you can put them in various other places.

- Have bundler put them in vendor or some such subdir, when you start
the project, and that will get deleted along with the project
