How do I run a Ruby Gem?

It seems that Debian/Ubuntu drops ruby gems into /var/lib/gems/1.8/bin.

So the solution (at least for Ubuntu/Debian) is:

$ sudo -s# echo 'PATH=/var/lib/gems/1.8/bin:$PATH' > /etc/profile.d/gemspath.sh# chmod 0755 /etc/profile.d/gemspath.sh

...and then open a new shell session.

(This is fixed in Ubuntu 11.10.)

If you happen to have installed Ruby through rbenv, you'll need to execute the following command

rbenv rehash

ruby rubygems sass

On macOS I had to add the gem executable directory to the path.
Add these lines to your ~/.bashrc file, and reopen the terminal to refresh the env vars.

# gem                                                                      gembin=`(gem env | sed -n "s/.*EXECUTABLE DIRECTORY: \(.*\)/\1/p")`export PATH=$gembin:$PATH
