mac MySQL升级后mysqlclient安装失败

今天无意间把MySQL升级到了8.0.22_1，然后pip安装mysqlclient发现会报以下错误：

根据报错内容查了一下/usr/local/Cellar/mysql-connector-c/6.1.11/include这个文件夹发现，文件夹就不存在，根据路径可以看出来这个查找的版本还是6.1.11，到/usr/local/Cellar/mysql-connector-c/文件夹看了一下，发现里面只有一个8.0.22_1的文件夹，刚好8.0.22_1里面有mysql.h这个文件，突发奇想，能不能复制一个改名为6.1.11，说干就干：

cd /usr/local/Cellar/mysql-connector-c/
cp -r 8.0.22_1 6.1.11

重试了一下，发现依然找不到mysql.h，仔细看了一下路径，发现/usr/local/Cellar/mysql-connector-c/6.1.11/include下多了一层mysql的文件夹，把mysql文件夹里的数据文件全部提到/usr/local/Cellar/mysql-connector-c/6.1.11/include这一层。

cd 6.1.11/include
cp -r mysql/* ../include/
