When ever you are trying to install a Ruby, package or anything else with RVM it is not that uncommon to run into strange issues. Just like when you first go to smashing the Ctrl + Alt + Delete keys on Windows, I have found through experience that the first port of call should be to take the following simple steps.
For an example, imagine you are trying to install Ruby 1.9.2. I recently had to use this approach to get version 1.9.2 installed on OSX Lion.
Note: On OSX, Make sure you have either the GCC libraries or XCode 4.2+ installed to work best with RVM
- rvm get head
- rvm reload
- rvm remove 1.9.2
- rvm install 1.9.2
First we update RVM, reload the environment (important) remove whatever broken ruby/package you are trying to get working. Finally, Install it fresh.
You would be suprised how often this resolves issues. Give it a try next time you are having issues.
