mac 解决mysqlclient安装失败问题

环境 mac
本人下载mysql 是采用brew 下载，所以安装路径在/usr/local/Cellar/mysql/8.0.19_1/

brew install mysql
brew install mysql-connector-c
sudo sed -i -e 's/libs="$libs -l "/libs="$libs -lmysqlclient -lssl -lcrypto"/g' /usr/local/mysql/bin/mysql_config
下载mysql-client
brew install mysql-client
路径在：/usr/local/Cellar/mysql-client/8.0.19/

采用Django启动项目报错
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.

Did you install mysqlclient?

下载mysqlclient
pip install mysqlclient
下载时报错
报错 1：
