试图安装橡胶宝石，Nokogiri 搞砸了？

Question

我正在尝试安装橡胶宝石。几天前，我在玩弄 Nokogiri，但无法正确安装。我忘了它，因为它不紧迫。好吧，现在我正在尝试安装橡胶 gem，但遇到了这些让我感到困惑的错误，它们似乎与 Nokogiri 有关，据我所知，它没有安装。帮帮我，谢谢。

这样做：sudo apt-get install libxslt-dev libxml2-dev 然后重新安装橡胶

错误信息很清楚：缺少libxml2。请访问http://nokogiri.org/tutorials/installing_nokogiri.html 获取安装依赖项的帮助。
