Since you have both RAILS 3.0.0 and 2.3.5, RAILS 3.0.0 is gettting loaded first. You can either uninstall the RAILS 3.0.0 GEM, or migrate your RAILS 2.3.5 App to use bundler. ([Gem Bundler – Manage your Ruby gems](http://gembundler.com/rails23.html)). Regards, Srikanth ---

Ah okay. That works. I have uninstalled 3.0.0. (For them with the same problem: gem uninstall rails --version 3.0.0) Thank you Srikanth ---

How have you done this? The correct way involves setting RAILS\_GEM\_VERSION in config/environment.rb. Is that what you did? There was no need for you to remove Rails 3. Your project should still be able to run the older version. > I want to install the OpenSource Project webpraca.
