无法加载 WSGI 应用程序“mysite.wsgi.application”；导入模块时出错

Question

我使用 django 3.1.1 和 Python 3.8.5。我想创建简单的博客。我使用一些旧代码，其中程序员可能使用 django 1.11，所以我改变了很多东西，但现在我陷入困境我收到错误    raise ImproperlyConfigured(django.core.exceptions.ImproperlyConfigured: WSGI application 'mysite.wsgi.application' could not be loaded; Error importing module.当我尝试删除时WSGI_APPLICATION = 'mysite.wsgi.application'我收到一个错误ImportError: Module "django.contrib.auth.middleware" does not define a "SessionAuthenticationMiddleware" attribute/class这是我的整个设置.py"""Django settings for mysite project.Generated by 'django-admin startproject' using Django 1.8.6.For more information on this file, seehttps://docs.djangoproject.com/en/1.8/topics/settings/For the full list of settings and their values, seehttps://docs.djangoproject.com/en/1.8/ref/settings/"""# Build paths inside the project like this: os.path.join(BASE_DIR, ...)import osBASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))# Quick-start development settings - unsuitable for production# See https://docs.djangoproject.com/en/1.8/howto/deployment/checklist/# SECURITY WARNING: keep the secret key used in production secret!SECRET_KEY = '*s@w*wx_w23k5vp%c%*aatqr42dsu3m$^(et@a(yrx$(4j-u*o'# SECURITY WARNING: don't run with debug turned on in production!DEBUG = TrueALLOWED_HOSTS = []SITE_ID = 1# Application definitionINSTALLED_APPS = (    'django.contrib.admin',    'django.contrib.auth',    'django.contrib.contenttypes',    'django.contrib.sessions',    'django.contrib.messages',    'django.contrib.staticfiles',    'django.contrib.sites',    'django.contrib.sitemaps',    'blog',    'taggit',    'haystack',)

Answer 1

某些中间件已过时或已移动/重命名。尝试使用 django 3 中的默认中间件列表：

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.middleware.common.CommonMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware',

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

Answer 2

我得到了同样的错误：

django.core.exceptions.ImproperlyConfigured：无法加载 WSGI 应用程序“core.wsgi.application”；导入模块时出错。

当我将项目中未安装的包“hello”MIDDLEWARE添加到中时settings.py：

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'corsheaders.middleware.CorsMiddleware',

    'django.middleware.common.CommonMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware',

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

    'hello', # 'hello' package doesn't exist

]

MIDDLEWARE因此，在将它们添加到以下位置之前，不要忘记安装所需的软件包settings.py：

pip install <package>
