Question

I have installed two different rails versions in my system (Fedora).

gem list -d rails
*** LOCAL GEMS ***

rails (3.0.5, 1.2.1)
    Author: David Heinemeier Hansson
    Rubyforge: http://rubyforge.org/projects/rails
    Homepage: http://www.rubyonrails.org
    Installed at (3.0.5): /usr/local/lib/ruby/gems/1.8
                 (1.2.1): /usr/local/lib/ruby/gems/1.8

    Full-stack web application framework.

When i try to create the project like following way (“http://www.nomachetejuggling.com/2008/03/12/using-multiple-versions-of-rails/“)

rails 1.2.1 myproject

But, it’s not working. So, i checked

rails -v
Rails 3.0.5

So, can you help me, how to create the project with older version and newer version. Is there any way to set the particular rails version as default?

Answer 1

To use an older version than the latest you have installed, just wrap the version number in underscores:

rails _1.2.1_ myproject
