macOS Mojave上的gcc损坏

Question

看来我的gcc坏了。

当我尝试从PyPI安装软件包时，出现以下错误：

    ./uwsgi.h:165:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
         ^~~~~~~~~
1 error generated.
In file included from core/protocol.c:1:
./uwsgi.h:165:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
         ^~~~~~~~~
1 error generated.

XCode命令行工具已安装：

    ?  xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

并从brew安装gcc：

?  brew install gcc
Warning: gcc 8.2.0 is already installed and up-to-date
To reinstall 8.2.0, run `brew reinstall gcc`

当我尝试识别使用哪个gcc时/usr/bin/gcc。我认为这是XCode版本。

但是brew中没有gcc二进制文件：

?  ls /usr/local/bin/gcc-*
/usr/local/bin/gcc-8        /usr/local/bin/gcc-ar-8     /usr/local/bin/gcc-nm-8     /usr/local/bin/gcc-ranlib-8

在这种情况下我该怎么办？如何修复gcc？

默认情况下，新的Xcode不提供标头。您应该手动安装它：

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
