Ruby 1.8.7

Rails 2.3.8

Rubgems 1.6.1

Any Idea !

I had installed list of different rails version(3.0.0,2.3.11,2.3.9). After uninstalling rails 3.0.0. Removed all the 3.0.0 gems like actionmailer,activemodel,activeresource etc. Application is working now.

Did you run ?

bundle install

Well I'm not sure if this command even exists in rails 2.3. Let me know.
