Problem with ri + rvm + Textmate

Question

I'm trying to lookup help for Ruby methods in Textmate through the Ctrl+H shortcut, but I'm always getting this error:

/Users/tomdeleu/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems.rb:388:in bin_path': can't find gem rdoc ([">= 0"]) with executable ri (Gem::GemNotFoundException) from /Users/tomdeleu/.rvm/gems/ruby-1.9.2-p180/bin/ri:19:in '

Platform:

• MacOS X 10.6.8
• RVM 1.6.20
• Textmate 1.5.10 (1631)
• TM_RUBY set to /Users/tomdeleu/.rvm/bin/rvm-auto-ruby
• installed osx-plist update as detailed in the RVM integration docs
• installed DrNic's Rails bundle

Ri works fine from the command-line (I ran "rvm docs generate" to install docs for 1.9.2). I've searched around but can't find a solution. Can anyone help?

Answer 1

After a lot of searching (and asking) around, solved it by reinstalling both Textmate (including delete of all customizations), and Ruby 1.9.2 (through RVM).
Afterwards I installed the osx-plist update + some bundles again. Note that the osx-plist update (as detailed here ) should be done with system Ruby, not a Ruby 1.9, otherwise other errors occur.
Also in Textmate make sure the PATH variable does not have a custom Ruby before your system Ruby.
With these settings, everything works fine now. Hopefully this is useful to anyone encountering this error in the future...
