Question

我是 django 新手，我正在运行命令

python manage.py migrate

并收到此错误。

Answer 1

因为我应该神奇地知道你的settings.py数据库配置，并且我的帖子因没有回答问题而不“要求提问者澄清”而被删除，所以我重新发布以尝试提供帮助。 mysql 数据库中 root 用户的默认密码是“”，即留空。现在您的数据库与您在 settings.py 文件中提供的配置不匹配。进入您的 dbms 并确保数据库的设置与您在 settings.py 中提供的设置匹配。

DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'NAME': 'DB NAME',
            'USER': 'USER NAME',
            'PASSWORD':'USER PW',
            'HOST' : 'localhost',
        }
    }

如果这些与您的数据库匹配，您现在应该可以迁移。
