Install Ruby Using RVM on Virtual Machine Running Debian Failed Silently

I've successfully installed a Debian guest operating system on a Vista host using VirtualBox. I'm trying to follow t开发者_运维知识库his tutorial(http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you) to install RVM and Ruby. It appears to install ruby successfully, but the terminal will not recognise ruby at all.

Here is the terminal output:

user@debian:~$ rvm install 1.9.2

user@debian:~$ ruby -v

I have no idea what went wrong or how to proceed here. I'd appreciate any insight anyone could offer.

Thanks

Try rvm use 1.9.2. Right now it's probably defaulting to the system ruby, and if you don't have a system ruby, well, it's defaulting to nothing.

If you want to make this stick between shell sessions: rvm use --default 1.9.2

$ rvm 1.9.2

will do the trick.
