Question

我正在使用OSX Yosemite，我在自制软件中安装了import requests import json dest = 'https://github.com/timeline.json' ## make the get request and store response res = requests.get(dest) ## you might want to check if respond code is correct by accessing attribute status_code ## Get the body of the respond as text body = res.text ## load json string ( text ) into dictionary res_dict = json.loads(body) ## json is now a dict assert 'messages' in res_dict assert 'documentation_url' in res_dict。

以下程序在编译时失败（例如gcc-4.8）：

gcc-4.8 main.c

错误：

#include <stdio.h>    

int main(void)
{
    printf("hello world");

    return 0;
}

和

main.c:8:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

产量

 $`gcc-4.8 -print-prog-name=cc1` -v

和

ignoring nonexistent directory "/usr/local/Cellar/gcc48/4.8.4/lib/gcc/4.8/gcc/x86_64-apple-darwin14.3.0/4.8.4/../../../../../../x86_64-apple-darwin14.3.0/include"

$ find /usr/local/ -name "stdio.h" -print

现在我知道我可以通过/usr/local//Cellar/gcc/5.2.0/include/c++/5.2.0/tr1/stdio.h /usr/local//Cellar/gcc/5.2.0/lib/gcc/5/gcc/x86_64-apple-darwin14.4.0/5.2.0/include/ssp/stdio.h /usr/local//Cellar/gcc48/4.8.4/include/c++/4.8.4/tr1/stdio.h /usr/local//Cellar/gcc48/4.8.4/lib/gcc/4.8/gcc/x86_64-apple-darwin14.3.0/4.8.4/include/ssp/stdio.h /usr/local//include/c++/4.8.4/tr1/stdio.h /usr/local//lib/gcc/4.8/gcc/x86_64-apple-darwin14.3.0/4.8.4/include/ssp/stdio.h让编译器找到正确的头文件，但为了善良，这是-I /path/to/directory！我不想为愚蠢的小程序做这件事。我该如何解决这个缺陷？

我最终删除了brew配方并重新安装。它现在有效，我还不清楚它何时/何时被破坏。

修改事实证明，这个问题已经发生过好几次了。每次升级OSX或Xcode时都会发生这种情况。

gcc48（从自制软件下载）找不到stdio.h
