How can I generate older rails application when current version is 3.0.3

I have 2 different Rails Rubygems installed on my Linux OS [2.3.8 and 3.0.3], but the current active Rails version is 3.0.3. So is it possible to generate Rails app using 2.3.8 style generator:rails testapp not new one: rails new testapp?


I'd recommend installing RVM and setting up different gemsets for each version of Rails. That way you can easily switch between Rails versions by just switching gemsets.

You can tell Rails to use version 2.3.8 like this:

rails _2.3.8_ testapp
