Q:

Change version of Ruby on Rails

I'm trying to install a CMS that requires Ruby on Rails 3.2.x, which I presume means any version of Ruby on Rails that supersedes 3.2.0.
So I installed Rails version 3.2.8, but I can't use it.
Could someone explain what's going on here? Also, if a project requires 3.2.x does that mean I include it in the project's gemfile, or do I have to install it as I'm trying to do here?

A:

To specify the version of rails you want to use, in your gemfile:
gem 'rails', 'version'
Change version to the version you want then run $ bundle install
