python安装问题

一：python3 pip3 install mysqlclient mac电脑安装错误

主要报错如下：

Failed to build mysqlclient

在这里深情提示一下，一定要看一下你的openssl安装的目录，我是用brew安装的，所以我的目录是：/usr/local/opt/openssl@1.1，大佬请注意那个@1.1，我真是个SB一开始没注意。
然后我根据网上的解决办法
LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysqlclient
我换成我的：

LDFLAGS=-L/usr/local/opt/openssl@1.1/lib pip install mysqlclient

然后就成了，搞了我一天，我真是ZZ
