Djangoscar演示错误，无法导入profile mod

Question

我下载了django oscar并尝试在应用程序中运行demo。当我尝试运行demo时，iam得到的错误是“cannotimportprofilemodel”。网址.py此演示中的文件名为

from apps.app import application
from datacash.dashboard.app import application as datacash_app
from oscar.views import handler500, handler404, handler403

admin.autodiscover()

urlpatterns = patterns('',
    (r'^admin/', include(admin.site.urls)),

    # Stores extension
    (r'^stores/', include(stores_app.urls)),
    (r'^dashboard/stores/', include(dashboard_app.urls)),

    # PayPal extension
    (r'^checkout/paypal/', include('paypal.express.urls')),

    # Datacash extension
    (r'^dashboard/datacash/', include(datacash_app.urls)),

    (r'', include(application.urls)),
)

请给我一些建议来纠正这个问题。提前谢谢。在
