Question

我很困惑如何从终端使用'python manage.py createsuperuser'命令。

当我运行此命令时，它会说

django.db.utils.IntegrityError：重复键值违反唯一约束“authtoken_token_user_id_key” 详细信息：Key（user_id）=（abcdef@gmail.com）已存在。

但是，在使用此命令之前，我删除了数据库并在删除迁移目录中的000 *文件后重新创建。

我检查过authtoken_token和user表中没有行。我不知道出了什么问题。

请给我一些建议。

Django createsuperuser说密钥已经存在
