Django: No module named 'app'

Question

Django barfs with

ImportError at /store/ No module named store 

But there is a debug message, there is a parameter

 INSTALLED_APPS = ('django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.admin', 'django.contrib.admindocs', 'store') Environment: Request Method: GET Request URL: http://localhost:8000/ Django Version: 1.4.5 Python Version: 2.7.3 Installed Applications: ('django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.admin', 'django.contrib.admindocs', 'store') Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware') Traceback: File "/usr/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response 111. response = callback(request, *callback_args, **callback_kwargs) File "/home/paul/cs462/store/store/views.py" in main 37. return redirect(reverse('django.contrib.auth.views.login')) File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in reverse 476. return iri_to_uri(resolver._reverse_with_prefix(view, prefix, *args, **kwargs)) File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in _reverse_with_prefix 363. possibilities = self.reverse_dict.getlist(lookup_view) File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in reverse_dict 276. self._populate() File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in _populate 253. for name in pattern.reverse_dict: File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in reverse_dict 276. self._populate() File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in _populate 265. lookups.appendlist(pattern.callback, (bits, p_pattern, pattern.default_args)) File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in callback 216. self._callback = get_callable(self._callback_str) File "/usr/lib/python2.7/site-packages/django/utils/functional.py" in wrapper 27. result = func(*args) File "/usr/lib/python2.7/site-packages/django/core/urlresolvers.py" in get_callable 105. not module_has_submodule(import_module(parentmod), submod)): File "/usr/lib/python2.7/site-packages/django/utils/importlib.py" in import_module 35. __import__(name) Exception Type: ImportError at / Exception Value: No module named store 

The shell works just fine (for what I'm trying), but this error appears on every page that I have. Does "store" in applications mean that the module is imported?

EDIT: I used Django many times for a project. It worked a few hours ago. There is an empty __init__.py file in the repository. Moreover, using the print operator, I was able to determine that this is being done (twice). urls.py and models.py also executed (but not views.py ). I have no idea what I can do to get this error.

If not for version control, I would never have found this. As it was, it took me almost an hour to track it.

The error was in the /urls.py store:

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

I moved the last URL from the url.py project to this application that used the abbreviated "store.views" to add each of the views.

He should have appeared:

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