我在我的窗户上安装 Rails 3。我安装了最新的 ruby 2.0.0,并更新了 gems。但是当我使用 gem install rails 安装rails时,成功的消息来了,但最后我发现了
ERROR: Error installing rails:
The 'atomic' native gem requires installed build tools
Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'
请帮助我...
