This gem contains only the Ruby libraries for the RVM Ruby API.
In order to install RVM please use one of the methods listed in the documentation
http://rvm.beginrescueend.com/rvm/install/
such as,
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-latest )
followed by placing the sourcing line in your ~/.bash_profile or wherever may
be appropriate for your setup (example, .zshenv, /etc/profile, ...):
-s "$HOME/.rvm/scripts/rvm" && . "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
After completing setup please open a new shell to use RVM and be sure to run
'rvm notes' to gain a list of dependencies to install before installing the
first Ruby. You can read more details about this process on the above
mentioned install page as well as the basics page:

Enjoy!
