fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.
error: command 'clang' failed with exit status 1
解决方法
export ARCHFLAGS="-arch x86_64"
然后再次安装mysqlclient即可。
原因
可以看到最后的错误写的是clang出错，大概率是编译器的问题，中间还报错了几次，architecture not supported，我猜测应该是新版本的xcode command tool默认使用的是arm版本的编译方式，而如果是x86架构，则需要通过环境变量指定使用何种架构。
