如何在rhel5上安装nokogiri gem？
我想安装gitlab，因此我需要安装一些宝石。 从而我得到以下错误：
Installing nokogiri (1.5.9)

An error occurred while installing nokogiri (1.5.9), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.9'` succeeds before bundling.
关于我的系统： RHEL 5.3，GCC44，G ++ 44，Python26，ruby 1.9.3p0，ruby-devel 1.9.1
我已经检查了nokogiri的每个安装指南，但错误并未消失：
例如
sudo gem install nokogiri -- --with-xml2-lib=/usr/local/lib
--with-xml2-include=/usr/local/include/libxml2
--with-xslt-lib=/usr/local/lib
--with-xslt-include=/usr/local/include
还有我已经安装的必要依赖项：libxml，libxml2-devel，libxml2，libxslt，libxslt-devel ...
有没有人有想法，我该如何解决这个问题？
好的，现在我已经解决了这个问题，如下所示：
1. libxml2 updated to libxml2-2.7.8
2. libxslt updated to libxslt-1.1.20
3. Again followed this installation guide:
