Gem unf_ext无法构建gem原生扩展
env => Mac。 OS优胜美地。
我有一个项目使用ruby 2.1.3。 但是当我捆绑安装时，出现了一个我无法解决的错误。 gem unf_ext有问题
这是我的终端消息：
$ gem install unf_ext -v '0.0.6' Building native extensions. This could take a while...

这是新的xcode工具中的一个错误。 在我的案例中，它打破了eventmachine。 有关使用虚拟文件和重新安装链接的答案更新OSX命令行工具6.3后，请参阅缺少C ++标头<__ debug> 。 我降级到6.2，问题消失了。
