How can I remove RVM (Ruby Version Manager) from my system?
For other shell newbies trying to fix the PATH variable
After following instructions in accepted answer, check and modify your PATH variable if necessary :
env | grep PATH
if you see "rvm" anywhere, you need to figure out where you are setting PATH and modify. I was setting it in 3 files - so check all the following files:
vim .bashrc
Delete the lines in the file referencing rvm using the dd command. :wq to save and exit.
source .bashrc to "reload"
Repeat this process (starting with the vim command) for .profile and .bash_profile
