任何建议？

解决方案

这是新的xcode工具中的一个错误。在我的情况下，它打破了事件机器。请参阅缺少C ++头文件< __ debug>在更新OSX命令行工具6.3之后以查找含有虚拟文件和重新安装链接的答案。我降级到6.2，问题就消失了。

I try brew update and xcode select install but still not work. Any suggestion?

解决方案

It's a bug in the new xcode tools. It broke eventmachine in my case. See Missing C++ header <__debug> after updating OSX Command Line Tools 6.3 for answers with dummy files and reinstallation links. I downgraded to 6.2 and the problem went away.
