Completely removing ruby from mac

Question

I have issues with building rails project, it simply says me about missing gems, while they present in system and properly configured. So whats the best way to completely remove ruby&rails from system(mac os). I already tried ways that found in google, but bug still present and i guess not all files&folders were removed from system

Answer 1

Ruby and Rails are both software that is very version dependent, bringing up even worse issues than the famed "dll hell" in Windows the best way to do this is to install RVM , which allows you to run multiple versions of Ruby and Rails on a single system. You can then switch to the version of Ruby and Rails you need, and run/build your app.
