RVM is installed on my machine (running Mac OSX 10.6.8), correctly and it runs fine. The odd thing is that to run it, I have to use source ~/.rvm/scripts/rvm for ev
source ~/.rvm/scripts/rvm
You have to make some settings.
Open terminal and run this command.
and then go to edit > Title and command and check Run command as login shell
edit > Title and command
Run command as login shell
and you are done. Now you don't need to specify source everytime.
