What is the correct way to uninstall Ruby installed by CLI ruby-install?
I have multiple Ruby versions installed under ~/.rubies using ruby-install:
ls .rubies
ruby-1.9.3-p545 ruby-2.0.0-p598 ruby-2.1.3 ruby-2.1.5
ruby-2.0.0-p451 ruby-2.1.2 ruby-2.1.4 ruby-2.2.0
I want to remove one of these versions. What is the proper way to uninstall Ruby installed by ruby-install?
