Ruby指向系统ruby而不是ubuntu中的rvm

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.

RVM要求您使用登录shell，默认情况下它不会打开，因此您需要手动执行此操作https://rvm.io/integration/gnome-terminal/
