我必须使用Django 1.8.5，因为1.5.5的支持已经在webfaction上结束了，1.4.22不会起作用。这是我现在使用1.8.5的错误日志

可能需要编辑wsgi才能使用django 1.8.5
"""
WSGI config for kb project.
This module contains the WSGI application used by Django's development server
and any production WSGI deployments. It should expose a module-level variable
named ``application``. Django's ``runserver`` and ``runfcgi`` commands discover
this application via the ``WSGI_APPLICATION`` setting.
Usually you will have the standard Django WSGI application here, but it also
might make sense to replace the whole Django WSGI application with a custom one
that later delegates to the Django one. For example, you could introduce WSGI
middleware here, or combine a Django application with an application of another
framework.

如果它解决了问题，我会全部升级，但如果不解决则不行。当我尝试使用1.4.22时出现此错误

Exception Value: cannot import name AbstractBaseUser
这是因为AbstractBaseUser没有在django 1.4.22中定义，我会重新导入所有这些并确保它们的工作比升级更难。
更新
我已将wsgi.py编辑为如下所示，然后重新启动服务器。
import os
import sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'kb.settings'
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

答案 0 :(得分：0)
您的升级路径太长了，如果您使用的是其他应用，则可能会发生重大变化。
相反，请执行下面的分阶段升级：
1.5 -> 1.6
1.6 -> 1.7
1.7 -> 1.8
这需要一段时间，但这就是长期保持如此重要升级的代价。
