I have installed Ruby via RVM on Linux Mint 11. It seems to have installed fine: when I enter type rvm | head -1, I get “rvm is a function” back. Entering ruby -v gives me 1.9.2p290. I can run ruby scripts from the bash terminal window fine. However, when I try to run the same scripts from say gvim (I’ve got a shortcut mapped to “ruby “) or geany or gedit (ditto), I get “ruby: command not found” (in gvim) or “ruby: not found” (in geany or gedit).
Here’s more information: “which ruby” gives me: $HOME/.rvm/rubies/ruby-1.9.2-p290/bin/ruby. $HOME/.rvm/rubies/ruby-1.9.2-p290/bin is in my path in my .bashrc. On another Linux Mint 11 machine, where all works fine, “which ruby” gives me $HOME/.rvm/bin/ruby. Also, on the machine where all is fine, I have a $HOME/bin folder that I don’t know where it came from, but was created the same day as my .rvm folder. It contains among other things, links to shell scripts in the $HOME/.rvm/wrappers folder.
I had same problem, you should try making shell login. To make so use the command “bash -l” instead of simply “bash”. In geany you can find where to change it in edit->preferences->terminal->shell
