I have executed the commands as prescribed in the instructions at the rvm website but things don\'t seem to work..
Fetching the code from the git repository runs smoothl
I just had a similar problem.
It turned out that many files in ~/.rvm/scripts/ and ~/.rvm/src/rvm/scripts/ which obviously should be executable did not have execute permissions. Running a script on both directories to set all files to executable solved that immediate problem.
