当我sudo gem install nokogiri在 Ubuntu 12.1 上运行时，我得到了这个。出了什么问题，我该如何解决？

jason@jason:~/ror/clss$ sudo gem install nokogiri
Building native extensions.  This could take a while...

尝试安装“libxslt-dev”和“libxml2-dev”包：

sudo apt-get install libxslt-dev libxml2-dev

说明在http://nokogiri.org/tutorials/installing_nokogiri.html

更新：

你需要sudo aptitude install ruby1.9.1-dev.
