I am actually reading a rails book that is written for rails 2.3.5. I want to test Rails 3 beta as well. Is it possible to have such a setup in my Mac OS leopard?
I have tried with gem list -d rails. There are many versions stored in my mac but I don't know how to use different versions of rails while creating applications using rails command
