合并Django1.5/python2和Django1.6/python3应用程序：ValueError at/需要超过1个值才能取消

Question

我正在尝试将现有的Django应用程序与现有的Django框架合并。这会导致一些问题，因为它们是使用不同的python/Django版本开发的，但是我进展得很好。你知道吗

我遇到了一只虫子，但我现在似乎无法控制自己。我确信我在做错事网址.py档案，但我似乎不知道到底是什么。 所以，我得到的错误是：

它似乎指向pi/urls.py文件。此文件看起来像：

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'pi.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^', include('kapstok.urls', namespace="kapstok")),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^prefscan/', include('prefscan.urls', namespace="prefscan")),
)

每当我注释掉url(r'^prefscan/', ...),行时，错误就会消失。你知道吗

prefscan/urls.py看起来像这样：

import django

    from django.conf.urls.defaults import patterns, include, url
else:
    from django.conf.urls import patterns, include, url

from django.template.loader import add_to_builtins

# Uncomment the next two lines to enable the admin:

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^prefscan/$',                                        'survey.views.login'),

    url(r'^prefscan/cc/staff/siteadmin/',                      include(admin.site.urls)),

    url(r'^prefscan/survey/keepalive/$',                       'survey.views.keep_alive'),
)

urlpatterns += staticfiles_urlpatterns()

js_info_dict = {
    'domain': 'djangojs',
    'packages': ('js'),
}

urlpatterns += patterns('',
    (r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),
)

urlpatterns += prefscan.ipblocker.core.urlpatterns

add_to_builtins('util.templatetags.closure_extras')
add_to_builtins('django.templatetags.i18n')

我只是不知道怎么回事！prefscan行似乎与kapstok行相同，后者工作时不会打嗝。你知道吗
