我的应用程序已与gunicorn + nginx一起部署，并且在我今天开始进行迁移之前运行良好。 现在该应用程序正在运行（顺便说一句，我不知道为什么会这样），但是我无法进入“管理”页面，登录后出现错误（我将DEBUG = True理解为了解情况）：
ProgrammingError at /admin/login/
relation "auth_user" does not exist
LINE 1: ...user"."is_active", "auth_user"."date_joined" FROM "auth_user...
在此之前我做了什么： 在几次失败的迁移尝试之后，我删除了数据库，并使用相同的名称再次创建了该数据库。然后
rm -rf <app>/migrations/
然后我尝试：
python3 manage.py migrate --fake
获取此内容：

我尝试了在google中可以找到的所有内容...不知道该怎么办
编辑：如果我只是进行makemigrations->迁移，我会收到相同的错误

在我的本地服务器中，所做的所有更改都可以正常工作。
答案 0 :(得分：0)
我通过将Django降级到2.2并删除了数据库来解决了这个问题。
