This Kind of Mis-Behavior frequently Derive from Using with rvman Unproper Shell Type.
Unfortunately the RVM Documentation Is Not Very Efficace in Addressing and Resolving this Issue…
This a General Troubleshooting that will Not Works Every Time, but will Simply Works in Some Cases…
So it’s Worth to Give it a Try :)

  1. Change the Shell to bash with: 

    bash

  2. On a Single User Installation Execute the Enabling Command: 

    source /home/USERNAME/.rvm/scripts/rvm

    (For Multi-User Install you will Find an Help Section Below…)

After the rvm Environment Should be Setup for Working Properly on a Bash Shell…

Then If you Need Further Help look:
