Exception Type: ImportError at /
Exception Value: No module named store

shell工作得很好（我尝试的），但是我的每个页面都会显示此错误。在应用程序中没有“存储”意味着导入模块???

编辑：我多次使用Django进行项目。这是几个小时前的工作。商店/中有一个空白__init__.py文件。而且，通过使用print语句，我能够确定它被执行（两次）。 urls.py和models.py也已执行（但不是views.py）。我不知道我能做些什么才能得到这个错误。

Answer 1

如果不是版本控制，我将永远不会发现这一点。事实上，我花了将近一个小时来追踪它。

错误在store / urls.py中：

urlpatterns = patterns('store.views',
    url(r'^$', 'main'),
    url(r'^new_delivery_user/$', 'new_delivery_user'),
    ...
    url(r'^event_signal/$', 'store.views.event_signal'), # problem
)

我已将项目url.py中的最后一个网址移动到此特定于应用的网址，该网址使用简写的“store.views”来预先添加每个视图。

应该出现了：

    url(r'^event_signal/$', 'event_signal'),

Answer 2

感谢Paul Draper，我更改了

re_path('api/(?P<version>(v1|v2))/', include('music.urls'))

进入：

    re_path('api/(?P<version>(v1|v2))/', include('musicservices.music.urls'))

问题解决了。

Django：没有名为'app'的模块
