I tried this many times I and keep getting the same error.

env: ruby: No such file or directory

I have “ruby=/opt/local/bin/ruby” in my environment and if I run ”/usr/bin/env ruby” shows it is responsive.

I tried added a path tag to ~/.MacOSX/environment.plist for a path to ”/opt/local/bin/ruby” with no luck.

I also tried changing ”#!/usr/bin/env ruby” in the script to ”#!/opt/local/bin/ruby” but that did not work either.

I am running Ruby version 1.8.6 and TextMate version 1.5.6 (1405).

I tried this on several macs with the same results.

Just trying this script as well. I have found that the first one works and the second one gives the error you have been describing. Haven’t isolated the cause yet but you could try using the first script and then looking at the difference between them.

Suspect the second script has been modified but not tested.
