【问题描述】：
我最近升级到 10.10 Yosemite 测试版，但在安装 Nokogiri 时遇到了问题。我正在使用 RVM 和 Ruby 1.9.3。我也遵循了here 的步骤，并尝试按照 Nokogiri 主页上的说明进行操作。
我已经通过自制软件安装了 libxml2 (2.9.1) 和 libxslt (1.1.28)，并尝试使用我的 Xcode 5 安装和 Xcode 6 beta 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:
ERROR: Failed to build gem native extension.

necessary libraries and/or headers. Check the mkmf.log file for more

You have to install development tools first.

有人知道如何解决这些安装错误吗？
编辑 6/10/14： 在尝试了几天在 OSX 10.10 上安装 Nokogiri 之后，我最终放弃了任务并在我的机器上恢复了 10.9。一些库和捆绑包需要更新才能在 10.10 环境中工作。

我已经安装了开发工具。我有 Xcode 6，我已经单独下载并安装了 10.10 的命令行工具。
-
希望这可能会有所帮助：*.com/questions/24091869/…
-
我设法解决了升级到 ruby 2.1.2（使用 rvm）的同样问题。经过一场噩梦般的宝石、啤酒和诸如此类的会议：/
-
我有一个非常相似的问题：OS X 10.10 (Yosemite)、RVM 1.26.3、Ruby 1.9.3 (ruby-1.9.3-p551)、Nokogiri 1.6.1。我尝试了 SO 和其他地方的各种想法，但到目前为止没有运气。
