python - 导入模块时出错 - 配置不正确 : WSGI application

Question

我最初使用名为 auth 的应用程序创建了一个 Django 项目，但遇到了一些错误，并将其更改为 authentication。后来，当尝试 runserver 时，我发现由于错误而无法运行:

django.core.exceptions.ImproperlyConfigured: WSGI application 'coolwebsite.wsgi.application' could not be loaded; Error importing module: 'No module named 'django.contrib.authentication''

所以我在网上查了一下，结果发现我不应该用与 Django 的应用程序结构相同的名称来命名应用程序。我将 authentication 更改为 oauth，但仍然收到相同的错误:

django.core.exceptions.ImproperlyConfigured: WSGI application 'coolwebsite.wsgi.application' could not be loaded; Error importing module: 'No module named 'django.contrib.oauth''

我将应用程序名称更改为birds，但仍然会收到相同的错误。我不明白为什么我仍然收到此错误。

完整的错误是:

django.core.exceptions.ImproperlyConfigured: WSGI application 'coolwebsite.wsgi.application' could not be loaded; Error importing module: 'No module named 'django.contrib.oauth''

我安装的应用程序:

INSTALLED_APPS = [
    ###APPS###
    'oauth.apps.OauthConfig',

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles'
]

为什么我会收到此错误？

Answer 1

因为这些模块都不存在。该应用程序名为“django.contrib.auth”。
