I had exactly the same problem after transferring to macOS High Sierra (though, errors were not the same, but similar).

I found a workaround by renaming /usr/local/include to /usr/local/include_old (well, name does not really matter, just the fact that g++/clang will not search for headers in this folder anymore).

网上查了下，据说是因为升级到新版本的mac版本导致的，可能是brew导致include错乱。

我试了重装brew不行，试了删除/usr/local/include 再重装也不行，最后解决方法如下：

1、xcode里面Header path去掉/usr/local/include

 

 2、复制一份/usr/local/include =》 /usr/local/include_old ，并且把上面的headerpath设置成这个

3、后来经过尝试，发现设置headerpath中有 /usr/local/include 可以，但是一定要是non-recursive，而且即使 /usr/local/include_old 设置这个路径，也一定要是non-recursive，否则会报同样的错误
