rvm: command not found MAC OX
===

really I don't know what happens, excuse me if this cuestion is so NOOB but I can't find the solution for this

>-bash: rvm: command not found

I tried this

>curl -L https://get.rvm.io | bash -s -- --version latest 

but still nothing I need to see the ruby version for use the simplecov because it not works with older version from 1.9
