Using RVM, but can't set current Ruby version (Ubuntu 11.10)

Question

I have recently installed RVM on a fresh install of Ubuntu 11.10 and can not work out how to start using a particular ruby version.

I have installed Ruby 1.8.7 and 1.9.2

RVM 1.6.9 is very old now. Did you install it through some package manager? If so, get rid of it and run the following in your bash shell:

curl -L https://get.rvm.io | bash -s stable

Then, place [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" in ~/.profile OR ~/.bash_profile OR ~/.bashrc

You should then be able to run type rvm | head -n 1 and it should say "rvm is a function".

Then you should be able to install rubies and use one of them. Be sure to use --default for that Ruby to remain the default even after you end your terminal session. E.g. rvm use ruby-1.9.2-p290 --default
