How to create a project with an older version of rails

I have installed Rails 3 on my local machine. Let's say I wan't to
create a new project but in version 2.3.5, can I do that?


Easiest way is probably to use an RVM gemset which just contains 2.3:

Yes you can do that . Install rails version 2.3.5 by using command gem install rails -v=2.3.5 . And for creating a project rails _v_2.3.5 . Use this command you will achive your result.

The command is:
$ rails _2.3.x_ [app_name]
