看错误信息是少了pkg-config
执行命令：brew install pkg-config，也报错！！！

解决方法：
mysqlclient安装
可以参考mysqlclient文档
首选确保你的macos已经安装配置好了brew，以及配置了国内源。
# 安装pkg-config
brew install pkg-config
注意：如果这里报错，先执行下brew install mysql；再执行brew install pkg-config命令
# 安装 mysql-client
brew install mysql-client@8.0
# 添加环境变量 在 ~/.zshrc 中添加下面这行
export PKG_CONFIG_PATH="$(brew --prefix)/opt/mysql-client@8.0/lib/pkgconfig"保存后 source ~/.zshrc 刷新环境变量通过 printenv 可以查看确认当前环境变量
接下来可以正常安装mysqlclient，这里我安装的是mysqlclient 2.2.7版本
注意⚠️：2.0.0 以上版本需要python3.8及以上才能兼容
pip3 install mysqlclient
如果正常安装完成，没有报错，进入当前python运行环境测试
如果能正常引入MySQLdb而没有报错，那么基本上算上顺利完成了。可以尝试在虚拟环境安装完依赖启动项目试试
