I’m working (on Mac OS X) with two installed ruby (apart from Apple default one): $ which ruby /opt/local/bin/ruby $ which ruby19 /opt/local/bin/ruby19 (all of the Ruby-1.9.0-0 bins have a “19” suffix) ## when i try a simple script as : #! /usr/bin/env ruby19 require “appscript” include Appscript ## p app(‘Finder’).home.folders.get ## i get the following : RubyMate r6354 running Ruby r1.9.0 (/opt/local/bin/ruby19) > > > desktop.rb ## /opt/local/lib/ruby/site\_ruby/1.8/\_aem/aemreference.rb:15:in `new' : Not a four-char-code string. ( ArgumentError ) from /opt/local/lib/ruby/site_ruby/1.8/_aem/aemreference.rb:15:in`pack\_enum’ from /opt/local/lib/ruby/site\_ruby/1.8/\_aem/aemreference.rb:204:in `' from /opt/local/lib/ruby/site_ruby/1.8/_aem/aemreference.rb:193:in`module:AEMReference’ from /opt/local/lib/ruby/site\_ruby/1.8/\_aem/aemreference.rb:44:in `' from /opt/local/lib/ruby/site_ruby/1.8/_aem/codecs.rb:8:in`require’ from /opt/local/lib/ruby/site\_ruby/1.8/\_aem/codecs.rb:8:in `' from /opt/local/lib/ruby/site_ruby/1.8/aem.rb:14:in`require’ from /opt/local/lib/ruby/site\_ruby/1.8/aem.rb:14:in `' from /opt/local/lib/ruby/site_ruby/1.8/aem.rb:10:in`\’ from /opt/local/lib/ruby/site\_ruby/1.8/appscript.rb:13:in `require' from /opt/local/lib/ruby/site_ruby/1.8/appscript.rb:13:in`module:Appscript’ from /opt/local/lib/ruby/site\_ruby/1.8/appscript.rb:7:in `' from /Users/yt/work/Ruby19/rb-appscript/Finder/desktop.rb:4:in`require’ from /Users/yt/work/Ruby19/rb-appscript/Finder/desktop.rb:4:in `’ then, ruby19 is looking into “/opt/local/lib/ruby/site\_ruby/1.8” i think this is due to my environment variables for Rubygems : $ echo $RUBYOPT rubygems $ echo $GEM\_HOME /opt/local/lib/ruby/gems/1.8 $ echo $RUBYLIB /opt/local/lib/ruby/:/opt/local/lib/ruby/site\_ruby/1.8 $ echo $RUBYGEMS /opt/local/lib/ruby/site\_ruby/1.8 is there a way to setup those environment variables to get ruby and ruby19 working with gems without switching an environment variable ? ---

See the “Important” paragraph in this section: > > [http://macromates.com/textmate/manual/shell\_commands#search\_path](http://macromates.com/textmate/manual/shell_commands#search_path) I knew that point, even if i forget it from time to time… In fact my “environment.plist” reproduces (thanks to some ruby script) nearly all of my environment variables taken from Zsh ones. The question is : are the values : RUBYOPT === rubygems GEM\_HOME === /opt/local/lib/ruby/gems/1.8 RUBYLIB === /opt/local/lib/ruby/:/opt/local/lib/ruby/site\_ruby/1.8 RUBYGEMS === /opt/local/lib/ruby/site\_ruby/1.8 still needed with ruby 1.9, are they wrong ? even if they were correct with ruby 1.8… i suspect there are wrong (at least RUBYGEMS) because I do have : $ ls -al /opt/local/lib/ruby/site\_ruby drwxr-xr-x 39 root admin 1326 22 déc 07:33 1.8 drwxr-xr-x 9 root admin 306 1 fév 08:11 1.9.0 drwxr-xr-x 4 root admin 136 8 déc 10:54 bin drwxr-xr-x 6 root admin 204 8 déc 10:54 lib -rw-r–r-- 2 root admin 509 5 avr 2007 site-specific.rb then, the error speaking about : “/opt/local/lib/ruby/site\_ruby/1.8/\_aem/aemreference.rb” because this file isn’t the right one for ruby19, the right one being : “/opt/local/lib/ruby/site\_ruby/1.9.0/\_aem/aemreference.rb” unfortunately i don’t know how RubyGems is able to find the correct gem, depending of the running ruby version ??? may be i’d have to change RUBYGEMS to : RUBYGEMS === /opt/local/lib/ruby/site\_ruby to let RubyGem choose by itself ??? ---

(ArgumentError) Oh, in that case, your Ruby install is broken and I’m out of good ideas. 🙂 James Edward G. II
