Question

我正在使用Django 2。我正在获取此错误代码，我在网上查找了所有内容，但没有找到任何解决办法来修复为何不断向我提供此错误代码的问题。

Traceback (most recent call last):

    "INSTALLED_APPS." % (module, name)
RuntimeError: Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

我安装的应用程序是：

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

出于某种原因，我得到了人们推荐的所有应用程序，无论如何，我都会尝试它们，并且得到相同的错误代码。我现在能想到的是，进一步的Django代码还是有问题。

Answer 1

INSTALLED_APPS = ['django.contrib.admin'，'django.contrib.auth'，'django.contrib.auth.views'，'django.contrib.contenttypes'，'django.contrib.sessions'，'django .contrib.messages”，“ django.contrib.staticfiles”，“网站”，]

这应该有效。
