How do I change my Ruby version using RVM?

Question

I am not able to switch the current Ruby version:

➜  ~  rvm list

rvm rubies

   ruby-1.9.2-p290 [ x86_64 ]
   ruby-1.9.3-p0 [ x86_64 ]

➜  ~  rvm use ruby-1         


        

Answer 1

In my case on Ubuntu, the entry in ~/.bashrc had:

 [[ -s "$HOME/.rvm/scripts/rvm" ]] && ."$HOME/.rvm/scripts/rvm" # BAD

instead of:

 [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # WORKING

Notice the missing space between . and "$HOME.

Also, if this is the problem, you should also be noticing an error on top when you start your terminal.
