Looks like Yosemite updated the system Ruby location. What do you get with a which ruby on your system? Does /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby exist?

[jarias]

1.8 was updated since Mavericks you can use

/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby which should always point to the system Ruby.

Also it might be good not to assume only one ruby is in the path (RVM, RBenv, etc)

[tomas]

Good to know. Unfortunately, we can't rely on RVM/Rbenv rubies as we need to require 'osx/cocoa' which is only available on the system one.

[jarias]

Even better, I was just wandering if you guys look it up from the PATH since rbenv and rvm both modify the PATH and can give you a different set of issues.

[tomas]

Actually, I use rbenv and after calling rbenv --init the path to the ruby binary gets replaced by a shim:

$ which ruby
/home/tomas/.rbenv/shims/ruby

That's why we need to use the full path to the system one. :)

Ok, so the problem is that both Ruby 1.8 and RubyCocoa were removed from OS X in Yosemite.

Last night I ported the GUI code from RubyCocoa to PyObjC and it seems to work fine. I'll be pusing a new release in a few days including this change as well as some other fixes.

Cool :)
