“AUTH_USER_MODEL 指的是尚未安装的模型 '%s'” % settings.AUTH_USER_MODEL django.core.exceptions.ImproperlyConfigured：

Question

我正在学习 django restframework，当我在我的 settings.py 中尝试此 AUTH_USER_MODEL = 'homepage.Account' 时，我收到此错误 "AUTH_USER_MODEL 指的是模型 '%s'尚未安装” % settings.AUTH_USER_MODEL django.core.exceptions.ImproperlyConfigured：AUTH_USER_MODEL 指的是尚未安装的模型“homepage.Account”我无法进行迁移。

这是我的 settings.py

INSTALLED_APPS = [
    'homepage',
    'django_tables2',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.humanize',
    'rest_framework',
    'rest_framework.authtoken',
]
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.TokenAuthentication',

    ]
}

AUTH_USER_MODEL = 'homepage.Account'

这是我的文件树

也许先尝试运行迁移，然后在您的设置中设置 AUTH_USER_MODEL。
