Installing Rails ERROR on Windows XP: could not find rails locally or in a repository

I see a similar question here. However, that is related to installing on non-windows platform. I followed the instructions here and get error when I execute the following:-

gem install rails

The error is following:-

ERROR: http://gems.rubyforge.org/ does not appear to be a repository ERROR: could not find gem rails 开发者_运维百科locally or in a repository

I am trying to use v1.8.6-26. Any help is appreciated.

An excellent installer for a developer;

BitNami RubyStack greatly simplifies the development and deployment of Ruby on Rails applications. It includes ready-to-run versions of Apache, MySQL, Ruby and Rails and required dependencies. It can be deployed using a native installer, as a virtual machine or in the cloud.
