python - 我应该如何在 Google App Engine 项目中导入 django.middleware 类？

Question

我正在尝试将我的 Django 项目部署到 GAE。使用 appcfg.py 部署后，我在 GAE 中收到此错误。有人知道如何解决这个问题吗？

Traceback (most recent call last):
  File "/base/python27_runtime/python27_lib/versions/1/google/appengine/runtime 
  /wsgi.py", line 223, in Handle
  result = handler(dict(self._environ), self._StartResponse)
  File "/base/python27_runtime/python27_lib/versions/third_party/django-1.4/django
  /core/handlers/wsgi.py", line 219, in __call__
  self.load_middleware()
  File "/base/python27_runtime/python27_lib/versions/third_party/django-1.4/django
  /core/handlers/base.py", line 47, in load_middleware
  raise exceptions.ImproperlyConfigured('Error importing middleware %s: "%s"' % 
  (mw_module, e))

  ImproperlyConfigured: Error importing middleware django.middleware.cache: "No module 
  named memcache"

下一段代码展示了如何在我的项目中导入中间件类。设置:

from djangoappengine.settings_base import *

....

MIDDLEWARE_CLASSES = (
'django.middleware.cache.UpdateCacheMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.cache.FetchFromCacheMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
)

感谢您对此进行调查。
