在我安装 Django-userena 后，我的 django 版本有一个错误：1.9.5 我只是一步一步地安装 django-userena，但是当我迁移它时，发生了一个错误，我不知道如何解决它。

应用：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',

    'userena',
    'guardian',
    'easy_thumbnails',
    'accounts',    
]

Answer 1

./manage.py migrate

如果您的 Django 版本是 1.9 或更低，请使用

./manage.py syncdb

然后

python manage.py createsuperuser

有关https://github.com/django/django/blob/master/django/contrib/auth/forms.py 的更多详细信息

可能会有所帮助

Answer 2

  python manage.py migrate --run-syncdb  

此命令将查看哪些表未创建，并将创建所有需要的表。

Answer 3

我遇到了同样的错误并修复了同样的错误，我检查了所提到的错误表是否存在于连接的数据库中。不是。再次应用迁移，它起作用了。

python manage.py migrate

python manage.py makemigrations
