rvm and shell scripts

If you want to use a specific version of Ruby via RVM inside a shell script then you need to make sure that the environment is setup correctly.

The RVM site addresses that HERE for the case where RVM is installed in a user's home directory.

But on my server I have a system-wide installation. In that case you should have a /etc/rvmrc file with a default setup and you need to source this.

Your scripts should look something like this:

#!/bin/bash                                                                                                                                                 
source "/etc/rvmrc"

rvm use 1.9.2
