I have Rails 2.2.2 installed and get the following message when I try  
to generate the rails guides:

Family-iMac:expences Dad$ rake doc:guides  
(in /Users/Dad/Documents/Rails/Apps/expences)  
rake aborted!  
Don’t know how to build task ‘doc:guides’

(See full trace by running task with --trace)

You need to do from inside a Rails 2.2 app

Thank you, Pratik. You were right. Once I generated an app within  
Rails 2.2, and updated my RubyGems from 1.2.0 → 1.3.1 (http://  
[tinyurl.com/6qhxxm](http://tinyurl.com/6qhxxm)), everything worked fine.
