请让我知道我能做些什么来解决这个问题。我感谢所有的帮助，提前谢谢

您应该安装nokogiri依赖项：

brew install libxml2 --with-xml2-config
brew install libxslt

谢谢你的回复。当我尝试“sudo:apt-get:command-not-found”时，我得到了这个答案。我在视网膜MacBook Pro上使用了OSX Mountain Lion。我更新了答案。我不知道OSX，但我想应该可以。嘿，再次谢谢。我得到了“警告：libxml2-2.9.1已经安装”和“警告：libxslt-1.1.28已经安装”好的，我不知怎么地让它工作了。出于某种原因，我不得不重新安装水豚！
