RVM
It is used to help you install the Ruby environment, help you manage multiple Ruby environments, and help you manage the Ruby environment on which the Ruby application you develop uses the machine. The Ruby environment is not only Ruby itself, but also a third-party Ruby plug-in on which it depends. All are managed by RVM.
