我试图更改应用名称。这没有用，所以我试图改回去。这也不起作用，我删除了所有迁移和db.sqlite。现在，每当我尝试makemigrations或migrate时，都会出现此错误：
django.db.utils.OperationalError: no such table: django_site

django.db.utils.OperationalError: no such table: django_site
我尝试了以下答案，但它们并没有帮助我：No such table as django_site，Django 1.5.4: no such table: django_site in admin/
我真的不知道该怎么办。也许有人可以帮助我。
答案 0 :(得分：1)
从django.contrib.sites中的installed_apps中删除settings.py
然后运行：
python manage.py makemigrations
python manage.py migrate
将django.contrib.sites添加到您的installed_apps并运行：
python manage.py makemigrations
python manage.py migrate
应该这样做。
