RVM hijacks your ruby by modifying your $PATH

If RVM is switching rubies correctly, but you aren't seeing it, I assume
your path is not set up correctly to allow RVM to hijack it.

There are a few ways I know that this can happen:
1. RVM gives you a line to stick in your .bashrc (or .bash_profile, or
.profile, or possibly other filename, depending on your system). This adds
to the path the locations for the rubies and binaries that RVM is
maintaining. The line is
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

2. If you put that line in, then maybe you haven't loaded it into your
current shell session. You can source the file, or restart your terminal and
try again.

3. If you have a return in your bash profile (I don't know much about bash,
I assume it returns from the script itself, short-circuiting anything that
would come after it, such as your RVM lines)


If none of that is helpful, try checking out the troubleshooting section
near the bottom of http://rvm.beginrescueend.com/rvm/install/
