《Ruby on Rails社区网站建设》中的实例用的是哪个版本的rails?
因为这本书是翻译的，刚给你查了下英文版本，这样说

Software Required to Build RailsCoders
To develop a web application using Ruby on Rails, you need to install a few things installed on
your computer.
In this book, I am going to be using [color=red]Ruby on Rails version 1.2 [/color]and MySQL 5.0. If you already
have these installed and configured on your system, ensure that you have the latest version of
Rails installed by following the instructions in the “Upgrading Rails” section; then skip ahead
to the section called “Creating the Skeleton of a Rails Application.”

这本书使用的是[color=red]Rails 1.2版本[/color]MySQL是5.0，但是书中有一个小节讲了如何把例子升级到新版的Rails环境下
2.x的，只要是2以上的区别就不是很大，没有关系的。
倒，记成Javaeyer最近写的书了《Web开发大全——Ruby on Rails版》，貌似还不错
看看作者，有一半是Javaeyer：
