我已经运行了 gem update --system 和 brew install coreutils 但我仍然遇到同样的错误。

更新:回答
从 Apple Developer 下载并安装 commandlinetoolsosx10.10forxcode6.2.dmg .无需卸载任何东西。

Answer 1

这是新的 xcode 工具中的一个错误。就我而言，它破坏了 eventmachine。参见 Missing C++ header <__debug> after updating OSX Command Line Tools 6.3有关虚拟文件和重新安装链接的答案。我降级到 6.2，问题消失了。
