问题描述

这是“settings.py”中的数据库代码：

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'proj_15db',
    'USER': 'root',
    'PASSWORD': '1234',
    'HOST': 'localhost',
    'PORT': '3306',
}

}

成功键入“manage.py makemigrations”后，我然后键入“manage.py migrate”发生以下错误：所有基本代码都已成功完成，但是当我尝试迁移时，会发生以下情况

此错误与“找不到模块”有关。 这个问题如何解决，因为没有发现这样的错误，
