You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

Answer 1

Your console is not running as a login shell and hence have no access to rvm function. If you are running Ubuntu, you can:

1. Open console
2. Select Edit -> Profile Preferences
3. Select tab: Title and Command
4. Check box 'Run command as a login shell'
5. Restart terminal
