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

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 = [&nbsp; &nbsp; 'django.middleware.security.SecurityMiddleware',&nbsp; &nbsp; 'django.contrib.sessions.middleware.SessionMiddleware',&nbsp; &nbsp; 'corsheaders.middleware.CorsMiddleware',&nbsp; &nbsp; 'django.middleware.common.CommonMiddleware',&nbsp; &nbsp; 'django.middleware.csrf.CsrfViewMiddleware',&nbsp; &nbsp; 'django.contrib.auth.middleware.AuthenticationMiddleware',&nbsp; &nbsp; 'django.contrib.messages.middleware.MessageMiddleware',&nbsp; &nbsp; 'django.middleware.clickjacking.XFrameOptionsMiddleware',&nbsp; &nbsp; '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>
