From: Jason Hsu Date: 2011-08-29T09:15:22+09:00 Subject: The proper version of Ruby on Rails I'm going through the book _Head First Rails_, and I can't even make it through the first chapter, because I can't get everything working. Part of the problem is that I don't know what versions of Rails and Ruby I'm supposed to be using. I've read that every Ruby on Rails book is geared towards certain versions of Rails and Ruby, and if you're using the wrong version of something, you're busted. Unfortunately, the _Head First Rails_ book doesn't even specify what versions to use. Why does Ruby on Rails change so much from version to version? This wasn't a problem with Python or other languages. Am I even using a good book? Should I try another book instead, or would I still face the same issues? -- Jason Hsu Founder and lead developer of Swift Linux (http://www.swiftlinux.org)
