Question

我整天都在战斗，但我失败了。我与MYSQL数据库的连接有问题。我使用Linux Debian，尝试连接到本地数据库，但出了点问题：/。

附加的设置。py

# settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'dbDjango',
        'USER': 'user',
        'PASSWORD': '*******',
        'HOST': '127.0.0.1',
        'PORT': '3306',
    }

但是，当我使用

运行服务器时

python3.7 manage.py runserver程序会向我发送如下错误消息：

ImportError: cannot import name 'CLIENT' from 'MySQLdb.constants' (unknown location)

MySQL作为服务正在运行：

ervice mysql status
● mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; disabled; vendor preset: disabled)
   Active: active (running) since Thu 2019-10-03 00:14:56 CEST; 36min ago

我不知道，什么会造成麻烦：（（谢谢答案

无法在Django中连接到mysqldb“ ImportError：无法从'MySQLdb.constants'（未知位置）导入名称'CLIENT'”
