Ruby 在 OSX 10.10 Yosemite 上安装 Nokogiri

我最近升级到了优胜美地10.10测试版，但我在安装Nokogiri时遇到了麻烦.我正在使用RVM和Ruby 1.9.3.我也遵循了here个步骤，并try 按照Nokogiri主页上的说明进行操作.

我已经通过brew 软件安装了libxml2(2.9.1)和libxslt(1.1.28)，并try 使用Xcode 5安装版和Xcode 6测试版中的命令行工具.

gem install nokogiri -v '1.5.5'
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:

有人知道如何修复这些安装错误吗？

EDIT 6/10/14:在try 了几天将Nokogiri安装到OSX 10.10上之后，我最终放弃了任务，在我的机器上恢复了10.9.为了在10.10环境中工作，需要更新几个库和Bundle 包.
