Nokogiri 1.5.9 gem 没有安装在 Mac OS X Mavericks 上？

Question

昨晚我的系统更新为 Maverick，现在我无法从我的 gemfile 安装 Nokogiri。它抱怨找不到 libxml2，但 Maverick 附带了 libxml2。我也试过了

brew install --development libxml2

还有：

brew install --development libxslt

我仍然看到相同的错误消息。我已经粘贴了下面的错误消息，有人可以看看并告诉我接下来应该尝试什么吗？

mapte:config-renderer mapte$  gem install nokogiri -v '1.5.9'

Answer 1

对我来说，我必须安装开发者工具：

  xcode-select --install

然后确保打开 xcode 应用并接受许可。
我尝试从命令行执行此操作，但没有成功。

Answer 2

我要检查的第一件事是您的 /usr/include 不为空或缺少 libxml2.h 并考虑符号链接或以其他方式将您的 Xcode SDK /usr/include 暴露给 hombrew 进程：

应用商店版本如下，但您可以随意调整您可能希望使用的 beta/pre-release/GM/旧版本 Xcode 的路径，提供 parser.h 文件：

 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2/libxml/parser.h

下一步将确保自制程序与典型的三步舞保持同步：

 brew update
 brew outdated
 brew upgrade

此时，您可能需要根据您在问题中粘贴的输出实际列出 mkmf.log 文件中的确切错误消息。
