clang-4.0: warning: argument unused during compilation: '-L/usr/local/lib' [-Wunused-command-line-argument]

#include <stdio.h>
         ^~~~~~~~~

error: command 'clang' failed with exit status 1

见鬼, 这不是C最通用的库么? 咋还能找不到.

检查一下clang版本.

➜  src git:(develop) clang --version                                       
clang version 4.0.1 (tags/RELEASE_401/final)Target: x86_64-apple-darwin18.5.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm@4/bin

挺正常的…

有人说坏境变量问题, 导入一下试试.

export "CFLAGS=-I/usr/local/include -L/usr/local/lib"

无果.

又翻了一遍stackoverflow..

找到了这个.

cd /Library/Developer/CommandLineTools/Packages
open macOS_SDK_headers_for_macOS_xx.pgk
# macOS_SDK_headers_for_macOS_xx.pgk 对应自己的系统版本

跳出安装界面, 点点点…

It work!

愉快安装 pip install pycrypto.
