I’m installing ruby on rails on my OS X 10.7 machine and trying to follow along with this book: Agile Web Development with Rails.

Anyway I have installed Ruby 1.9.3 and then ran gem install rails and it pulled down rails 3.1.3, now the book says when I run ‘rails -v’ I should get 3.2.0 or NEWER.

I checked out http://rubygems.org/gems/rails and it says the latest version is rails 3.2.0 RC2, how is it that the book specifies (in multiple places to it’s not a typo) that it should be 3.2.0 or NEWER when 3.2.0 isn’t even released?

    Actually, if you want the latest unstable version, run this:

    gem install rails --pre

    It’ll install the latest RC.

    EDIT: as to why the included 3.2.0 when it is not out yet, I can’t answer for them! Maybe you have a “beta” version of the book?
