How do I set up Ruby on Rails?
How do I get “ruby” to do what “ruby1.9.1” does?
I installed ruby 1.9.3-p125 with rvm. rvm list yields
ruby-1.9.3-p125 [ x86_64 ]
rvm use 1.9.3-p125 yields
Using /usr/share/ruby-rvm/gems/ruby-1.9.3-p125
Running /usr/share/ruby-rvm/hooks/after_use
However, ruby --version is ruby 1.8.7, (which ruby is /usr/bin/ruby).
I also have two executables: ruby1.8 and ruby1.9.1, but nothing called ruby1.9.3 is on the path.
How do I actually get ruby to run ruby1.9.3 (or at the very least, how do I run it at all).
Once I can do that, I'd also like to uninstall the other ruby versions since they're just taking up space.
