I think you have two ruby installations: a ruby 1.8.6 installation that came with os x. that version of ruby has the rails gem installed, and running rails -v finds a /usr/bin/rails installed by ruby 1.8.6. You have since installed ruby 1.9.1, and ruby invokes that. That ruby install does not have the rails gem installed. you could verify this by playing with gem list (and looking at the difference between /usr/bin/gem list and /opt/local/bin/gem list ) Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
