django目前遇到的坑

到自己安装django的位置，例如我的/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/django/db/backends/base中base.py注释掉

if version < (1, 3, 3): 

    raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)

再次运行 python3 manage.py runserver会出现端口占用(我是8000)

lsof -i:8000

kill -9 25225
