        raise EnvironmentError("%s not found" % (_mysql_config_path,))
    OSError: mysql_config not found

解决方法如下：

安装 mysql-connector-c：

brew install mysql-connector-c

查找mysql_config的位置：

cd /usr/local/bin

find / -name mysql_config

输出：

/usr/local/bin/mysql_config
/usr/local/Cellar/mysql-connector-c/6.1.11/bin/mysql_config

将/usr/local/Cellar/mysql-connector-c/6.1.11/bin/mysql_config配置到环境变量中：

vi ~/.bash_profile

配置：

PATH=/bin:/usr/bin:/usr/local/bin/:usr/local/Cellar/mysql-connector-c/6.1.11/bin/:${PATH}
export PATH

其中usr/local/Cellar/mysql-connector-c/6.1.11/bin/为新配置的环境变量。

使新配置的~/.bash_profile生效：

source ~/.bash_profile

备注：如果没有效果，需要在pycharm中的终端运行source ~/.bash_profile

最后，执行安装命令即可：

pip install mysqlclient==1.4.4

最后，mysqlclient安装成功。
