报错原因分析: 找不到mysql的配置脚本

解决方案:
第一步: # https://github.com/PyMySQL/mysqlclient-python
  进入该链接,下载源码
第二步: 修改 `setup_posix.py `
在`setup_posix.py`内找到`mysql_config.path`
将`mysql_config.path` 替换` /xxx/xxx(mysql安装路径/bin/mysql_config)`
替换之后类似:   `f = popen("%s --%s" % ('/usr/local/mysql/bin/mysql_config', what))`
第三步:手动安装mysqlclient-python
`python setup.py install`
第四步:
`pip install Flask-MySQLdb`
 搞掂了!!!
