I tried using this https://github.com/matschaffer/win32-open3-19 as described in this post: http://stackoverflow.com/questions/4930270/ruby-1-9-no-such-file-to-load-win32-open3
But I never got it to work. Note that the "win32-open3 requires Ruby version < 1.9.0" So I used pik to downgrade to Ruby version 1.8.7, so I could use win32-open3, and then I was able to run the rails_upgrade plugin. Then I plan to upgrade my app using 1.8.7, make sure that works, and get that checked into version control. Once that's done I'll use pik to go back up to 1.9.* and make sure it still works. Don't forget to add gem "win32-open3" to your Gemfile, at least until you get the rails upgrade done (no need to check that into version control unless you are also checking in the rails upgrade plugin, which you probably won't). -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
