How to uninstall rvm, ruby, rails and gems. I'm getting errors on Mavericks

Question

I'm new on Ruby on Rails and I have some problems with configuration. I don't know what to do. I installed many times ruby, rails and Gems because report problems. I read a lot of questions on stack overflow and nothing for solve. I try now uninstalling everything and I have some errors when I trying to remove Gems, :

I report some problems on the terminal and I don't know how to send a log, etc.. It's that correct for uninstall:

Remove Gems: $ gem clean -Uninstall ruby: $ rvm uninstall ruby (#this will uninstall all ruby's installed?) or need: -Uninstall by version:

$ rvm uninstall 2.1.0 

and others version 2.0.0 and 2.1.1

-Uninstall rvm:

$ rvm repair
$ rvm cleanup
$ rvm implode

and for now install everything again!?

When I try I have this:

rm -rf ~/.rvm 

or

rvm implode
