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

A possible fix for ZSH users:

Somehow I had:

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

in both .zprofile and .zshrc.

Removing the line from .zprofile resolved the issue. (Though you should be able to remove from either, as long as it appears just once)

Answer 2

I had the same problem. Moving the line: [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

after the line from MacPorts: export PATH=/opt/local/bin:/opt/local/sbin:$PATH

solved the problem for me.

Answer 3

same pb here. line was there twice and it broke it.... for whatever reason... removing the extraneous line solved it

Answer 4

Moving this:

[[ -s "/usr/local/rvm/scripts/rvm" ]] && . "/usr/local/rvm/scripts/rvm"

in the bottom of ~/.bash_profile solved the problem for me.

Answer 5

Instead of:

rvm use 1.9.2 --default 

I used the full version:

rvm use ruby-1.9.2-p290 --default 

That worked for me in zsh.

Answer 6

sanity check - make sure that the project you are working on has the same ruby version that you try to set as default in the .ruby-version file.

it happened to me, and i couldn't figure out why rvm doesn't use my default
