Python 创建超级用户时出现Django错误，AttributeError:'；经理'；对象没有属性'；通过“自然”键获取'；

我使用的是Django版本1.11.3和djangorestframework版本3.6.3。在使用以下命令创建超级用户的阶段：

python manage.py createsuperuser

此命令本应询问我的电子邮件和密码，但它确实询问我的电子邮件，但在输入电子邮件后，我出现了一个错误：

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)

    self.UserModel._default_manager.db_manager(database).get_by_natural_key(username)
AttributeError: 'Manager' object has no attribute 'get_by_natural_key'

我还更新了settings.py中的应用程序定义：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'rest_framework.authtoken',
    'profiles_api',
]
AUTH_USER_MODEL = 'profiles_api.UserProfile'

---

我已尝试使用python2和python3执行此操作，但错误相同。

UserProfileManager

应从

BaseUserManager

类继承，而不是从

对象继承：

class UserProfileManager(BaseUserManager):
...

您可以找到实现自定义用户模型的示例

class UserProfileManager(BaseUserManager):
...
