Django - 导入错误：没有名为* .urls的模块

Question

我正在使用官方的Django教程，并使用Django 1.6.1版，Python 2.7.6稍微调整它以满足我自己的需要。

我正处于让我映射URL的地步，但是当有一个非常清楚的模块中有一个恰当命名的文件时，我一直得到“没有模块名为customers.urls”的错误，所以我真的不知道是什么我做错了。

我最初的想法是我需要在root / urls.py中导入与客户相关的内容，但导入的每个组合都会导致大致相同的错误，并且教程没有说这样做。

ROOT_URLCONF ='taco.urls'（taco是项目的名称）

我正在使用manage.py/runserver运行它，所以没有特殊的Web服务器技巧，我知道。 我重启了好几次。

应用程序都已正确注册，因为回溯可以证明。

关于我正在俯瞰的东西的任何指示将不胜感激！

根/ urls.py：

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

admin.autodiscover()

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

客户/ urls.py：

from django.conf.urls import patterns, url;

from customers import views;

urlpatterns = ('', 
    url(r'^$', views.index, name='index')
);

客户/ views.py：

from django.shortcuts import render
from django.http import HttpResponse;

def index(request):
    return HttpResponse("Hello");

Answer 1

在您的customers / urls.py中：

改变这个：

urlpatterns = ('', 
    url(r'^$', views.index, name='index')
);

为了这：

urlpatterns = patterns('', 
    url(r'^$', views.index, name='index')
);

另外，请确保在包customers有__init__.py文件。 并且INSTALLED_APPS正确地填充了您的应用名称。

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'south',
    'customers',
    'inventory',
    'lookups',
    'orders',
)

Answer 2

如果taco是项目的名称，请检查是否正确引用了应用程序，因此在已安装的应用程序中，您可能需要以下内容：

Installed Applications:
('django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'south',
 'customers',
 'inventory',
 'lookups',
 'orders')
