Fixing Textmate2 Ruby Bundle in Yosemite (Mac OSX 10.10)

bundlefix.txt

Using the Command-/ function to comment something out in Textmate2, I got the error:

	interpreter failed: No such file or directory
	
After some investigation, I realized that Yosemite is using Ruby 2.0 and the bundle here needed Ruby 1.8.
I use RVM to manage my Ruby virtual enviroments, and already had added a Ruby 1.8 into my collection. 
(Look at the RVM docs to see how.) So the shell command:

	which ruby
	
Got me:

	/Users/johnkeefe/.rvm/rubies/ruby-2.0.0-p247/bin/ruby
	
With some investigation into the "rubies" directory in that path, I found ruby-1.8.7-p374. 
So back in Textmate2, I forced the error again and clicked the "Edit Command" button. 
I then changed the first line of the bundle script from ...

	#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

to ...

	#!/Users/johnkeefe/.rvm/rubies/ruby-1.8.7-p374/bin/ruby
	
And it worked.
