在Windows上安装特定的Ruby on Rails版本

Question

Normally I use:

gem install rails

I can install Rails on Windows, but by default, I guess the latest version, version 3.0.3 is installed.

So if I want to install some other version of Rails, let's say 3.0.1, how can I do it?

Answer 1

Example:

gem install rails -v 3.0.1

Also, all the options for gem can be seen by running gem -h

A note:
If you're on *nix using RVM is highly recommended for Ruby management.
