Why doesn't “RVM --default” work for me on Mac

Question

After using Ruby and Rails for quite some time now, i wanted to try RVM. Everything works fine, except for one thing:

In a freshly opened Terminal ruby points to the system's ruby, despite the fact, that I used the rvm --default command.

user@terra ~ $ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10]
user@terra ~ $ which ruby
/opt/local/bin/ruby
user@terra ~ $ rvm list
   ruby-1.8.7-p334 [ ]
=> ruby-1.9.2-p180 [ ]

Everything is fine after I call rvm reload

user@terra ~ $ rvm reload
user@terra ~ $ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.7.1]
tmangner@terra ~ $ which ruby
/Users/user/.rvm/rubies/ruby-1.9.2-p180/bin/ruby

I've set up my .bash_profile as described in the documentation:

...
[[ -s "/Users/user/.rvm/scripts/rvm" ]] && source "/Users/user/.rvm/scripts/rvm" 

Thanks for your help. It is highly appreciated.

I'm using Mac OS X Snow Leopard (10.6.6)

Update:

That --default does not seem to work for me ...

user@terra ~ $ rvm use 1.9.2 --default
Using /Users/user/.rvm/gems/ruby-1.9.2-p180
user@terra ~ $ rvm default
user@terra ~ $

Answer 1

I had the same problem and since I use Oh-My-Zsh it was a little bit more difficult to track if I have duplicate calls to RVM.

I fixed it by moving the call to RVM from the separate rvm.zsh file located in my \custom folder inside \oh-my-zsh to the very end of my main .zshrc file.

It looks like RVM is really sensitive to being called not at the end of your zsh initialization sequence.

Answer 2

My issue was resolved by changing:

PATH=/usr/local/bin to PATH=$PATH:/usr/local/bin in my .zshrc

Obviously, you need to make sure RVM is properly installed first, and run the type rvm | head -1 check that @choise suggested. rvm use --default 1.9.3-p362 now works properly.

Answer 3

I had the same issue on Mac OS X 10.7.

And later I found that my account was not added to "rvm" group.

After I add myself to rvm group, I can set --default of rvm.

Answer 4

You need to put the path to rvm in front of your PATH

$ export PATH=/path/to/rvm-dir:$PATH

Answer 5

what does type rvm | head -1 print out?

in my bash_profile (on the latest osx) i had to put

# Ruby Version Manager
[[ -s "/usr/local/rvm/scripts/rvm" ]] && . "/usr/local/rvm/scripts/rvm"

i also created a gemset and setted this as default:

rvm reload
rvm install 1.9.2
rvm --create use 1.9.2@default
rvm --default use 1.9.2@default

I had the same problem once. Turned out the rvm-script got loaded twice, which broke things a bit.

Check all the files that get loaded when you open a shell, e.g. /etc/profile, ~/.bashrc, ~/.bash_profile and so on, and make sure they don't load RVM twice.

Maybe put echo "Going to load RVM" before [[ -s "/Users/user/.rvm/scripts/rvm" ]] && source "/Users/user/.rvm/scripts/rvm" in your ~/.bash_profile to see if it happens or not
