我试图更改应用名称。这没有用，所以我试图把它改回来。这也不起作用，我删除了所有迁移和我的 db.sqlite。现在，每当我尝试makemigrations或migrate收到此错误时：

django.db.utils.OperationalError: no such table: django_site

django.db.utils.OperationalError: no such table: django_site

我尝试了这些答案，但它们没有帮助我：没有这样的表 django_site，Django 1.5.4：没有这样的表：管理员/中的 django_site

我真的不知道该怎么办。也许有人可以帮助我。

我最近遇到了同样的问题，结果我Site.object.get_current()在其他地方使用，同时我将它添加'django.contrib.sites',到INSTALLED_APPSand SITE_ID=1。

After trying all solutions that I found here without luck. I comment the line Site.object.get_current() and execute

python manage.py makemigrations
python manage.py migrate

And it worked.

Those same lines didn't work when I've Site.object.get_current()

I assume that in some way it raises an error and is caught as a too global Exception class.

I'm using Django 3.2.10.

django.contrib.sites从您installed_apps的输入中删除settings.py

然后运行：

python manage.py makemigrations
python manage.py migrate

添加django.contrib.sites到您的installed_apps并运行：

python manage.py makemigrations
python manage.py migrate

那应该这样做。
