常见问题

ImproperlyConfigured: Middleware module "django.contrib.auth.middleware" does not define a "SessionAuthenticationMiddleware" class

?

运行python manage.py runserver时出现下面错误

Traceback (most recent call last):

? File "D:\Python27\lib\wsgiref\handlers.py", line 85, in run

??? self.result = application(self.environ, self.start_response)

? File "D:\Python27\lib\site-packages\django\contrib\staticfiles\handlers.py", line 72, in __call__

??? return self.application(environ, start_response)

? File "D:\Python27\lib\site-packages\django\core\handlers\wsgi.py", line 236, in __call__

??? self.load_middleware()

? File "D:\Python27\lib\site-packages\django\core\handlers\base.py", line 57, in load_middleware

??? raise exceptions.ImproperlyConfigured(‘Middleware module "%s" does not define a "%s" class‘ % (mw_module, mw_classname))

ImproperlyConfigured: Middleware module "django.contrib.auth.middleware" does not define a "SessionAuthenticationMiddleware" class

SessionAuthenticationMiddleware 这个是1.7里新加的，把 django版本升级就可以解决这个问题

?

如何查看 django版本？

import django

django.VERSION

?

还有一个方法是在 settings.py里删除SessionAuthenticationMiddleware

MIDDLEWARE_CLASSES = (

??? ‘django.contrib.sessions.middleware.SessionMiddleware‘,

??? ‘django.middleware.common.CommonMiddleware‘,

??? ‘django.middleware.csrf.CsrfViewMiddleware‘,

??? ‘django.contrib.auth.middleware.AuthenticationMiddleware‘,

??? ‘django.contrib.auth.middleware.SessionAuthenticationMiddleware‘ ,

??? ‘django.contrib.messages.middleware.MessageMiddleware‘,

??? ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘,

??? ‘django.middleware.security.SecurityMiddleware‘,

)
