我刚收到露比的讯息说 C:\Users\ndx>gem install awestruct Fetching: hpricot-0.8.6.gem (100%) ERROR: Error installing awestruct: The 'hpricot' 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' 为什么这些网址不可点击?(在终端中具有这样的功能会很酷)。
