无法安装Nokogiri

当我在Ubuntu 12.1上运行sudo gem install nokogiri时，我已经回来了。 怎么了，怎么解决？

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

Answer 1

尝试安装“libxslt-dev”和“libxml2-dev”软件包：

 sudo apt-get install libxslt-dev libxml2-dev

更新：

你需要sudo aptitude install ruby1.9.1-dev 。
