在mac环境下安装mysqldb时遇到编译错误，提示'cc'命令失败退出状态1。问题根源可能是gcc版本不兼容。通过搜索解决方案，发现无需卸载xcode和command-line-tools，而是通过设置环境变量CFLAGS和CPPFLAGS为-Qunused-arguments来将错误警告转化为警告，从而成功解决这个问题。

网上说是gcc版本不兼容的的问题
百度一下很多人将卸载xcode和commond-line-tools,但是这样太麻烦了 而且不知道怎么卸载
再百度得知
clang并不支持这个参数, 做一下修改把他改成warning.
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
这样就ok了.
