ruby - 在 Windows 上的 Ruby 1.9.1 上安装 Hpricot

Question

我正在尝试使用以下命令安装 hpricot:

>gem install hpricot -v 0.8.2
Building native extensions.  This could take a while...
ERROR:  Error installing hpricot:

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.</p>

它提到我需要安装“开发工具”，但我不知道那指的是什么。有什么建议吗？
