Question

I use ubuntu 11.10 and I have installed rvm and have installed ruby 1.9.3. My system has by default ruby 1.9.1. Hence instead of pointing to the ruby installed by rvm, my system points to the default ruby. How can I change this behaviour?

Answer 1

I’ll bet that you haven’t configured your path correctly. Try

echo $PATH

Ive got

/Users/matt/.rvm/rubies/ruby-1.9.3-p286/bin

before

/usr/bin

If that isnt the case for you, then you can add this little script to your .bashrc

I do this because sometimes I want to use system ruby and sometimes I want to use rvm rubies.

rvmenv() {
    [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.                                                                           
}
#rvmenv

If you want to use rvm all the time you can just uncomment the last line, or you can just run

rvmenv

in a shell session.
