【问题描述】：

我想安装 gitlab 因此我需要安装一些 gems。因此我得到以下错误：

Installing nokogiri (1.5.9)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/git/gitlab/vendor/bundle/ruby/1.9.1/gems/nokogiri-1.5.9 for inspection.

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, 红宝石 1.9.3p0, ruby-devel 1.9.1

我已经检查了 nokogiri 的每个安装指南，但错误并没有消失：

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：libxml、libxml2-devel、libxml2、libxslt、libxslt-devel...

有没有人知道如何解决这个问题？

【问题讨论】：

也许尝试不同版本的 Nokogiri？
这并不能解决我的问题...

标签： ruby gem nokogiri

【解决方案1】：

好的，现在我已经解决了如下问题：

1. libxml2 updated to libxml2-2.7.8
2. libxslt updated to libxslt-1.1.20
3. Again followed this installation guide:
