我跑了gem update --system,brew install coreutils但我仍然得到同样的错误.

Answer 1

这样做对我有用:

echo '#define _LIBCPP_ASSERT(x, m) ((void)0)' | sudo tee -a /Library/Developer/CommandLineTools/usr/include/c++/v1/__debug > /dev/null

然后又跑bundle了.

并且,由于这仅仅是Apple发布补丁之前的临时修复,因此请删除新创建的文件:

sudo rm /Library/Developer/CommandLineTools/usr/include/c++/v1/__debug

Answer 2

这是新的xcode工具中的一个错误.它打破了我的情况下的事件机器.有关使用虚拟文件和重新安装链接的答案,请参阅更新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.
