安装 mysql-python

$ sw_vers
ProductName:  Mac OS X
ProductVersion: 10.12.6
BuildVersion: 16G29

$ python -V
Python 2.7.14

某个项目开发要用到 MySQL-Python 库，然而 pip install 安装失败，goole 后找到解决方法，总结下。

出错：

mysql_config 在 Mac 下是由 mysql-connector-c 提供的

$ brew install mysql
$ brew install mysql-connector-c

但是安装完 mysql 相关依赖后依旧报错，后来搜到要修改 mysql_config 配置解决

$ which mysql_config
/usr/local/bin/mysql_config

$ vim /usr/local/bin/mysql_config

libs="$libs -l "
修改为
libs="$libs -lmysqlclient -lssl -lcrypto"

此时可成功安装
