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‘,

)

SNIMissingWarning & InsecurePlatformWarning

D:\virtualenv\lwc-ws>pip install django==1.8

Collecting django==1.8

InsecurePlatformWarning

解决方法：

在cmd中输入：

pip install pyopenssl ndg-httpsclient pyasn1

Could not find a version that satisfies the requirement djangocms-installer (from versions: )

No matching distribution found for djangocms-installer

使用-vvv打开debug信息

(django-cms) D:\virtualenv\django-cms>pip install djangocms-installer -vvv
Collecting djangocms-installer
1 location(s) to search for versions of djangocms-installer:
* https://pypi.python.org/simple/djangocms-installer/
Getting page https://pypi.python.org/simple/djangocms-installer/
Looking up "https://pypi.python.org/simple/djangocms-installer/" in the cache
No cache entry available

Starting new HTTPS connection (1): pypi.python.org

最后发现是fiddler开了的原因，关了就好了

django.core.exceptions.ImproperlyConfigured: LANGUAGE_CODE "zh-cn" must have a matching entry in LANGUAGES
