RVM installed by Ruby not working?

Question

I installed RVM using the single instruction mentioned at the RVM website (using git).

Then I installed Ruby version 1.9.2 and 1.8.7 using:

rvm insta

Are you making sure to source /usr/local/lib/rvm? echo 'source /usr/local/lib/rvm' >> ~/.bashrc and relog via SSH/start a new instance of Bash.

To clarify, since there is some confusion: there are two ways to install RVM: a "per user" install, and a "system wide" install.

For most day-to-day use, you want to use a "per user" install, which installs RVM into ~/.rvm. System-wide installs are good for servers, where one set of Rubies should be used. The default location for RVM in this case is /usr/local/rvm.

Based on your question, it appears you've installed RVM as a system-wide install.

To use RVM, it must be initialized by running a script each time you log in. To do this easily, you include the file in your ~/.bashrc file (or ~/.bash_profile if you're on OS X), so that it is automatically run each time you log in. For a per user install, add the following text to the file:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

for system wide installs, use this text instead:

[[ -s "/usr/local/lib/rvm" ]] && . "/usr/local/lib/rvm"

If you do indeed have a system-wide install, you will also need to make sure you are a member of the rvm group; type the following to do so:

sudo adduser `whoami` rvm

Once you have made the necessary changes, log out of your session and then log back in. Once you have done so, rvm use 1.9.2 should set a bunch of environment variables, which you can see by typing rvm info. If all is well, ruby should execute correctly.
