python之Django，教程之错误 : No module named urls

您好，我正在按照 Django 的教程制作第一个网络应用程序(link) 但是我得到了这个错误:

 File "c:\Python27\lib\site-packages\django\utils\autoreload.py", line 226, in wrapper 
    fn(*args, **kwargs) 
   File "c:\Python27\lib\site-packages\django\core\management\commands\runserver.py", line 121, in inner_run 
    self.check(display_num_errors=True) 
   File "c:\Python27\lib\site-packages\django\core\management\base.py", line 374, in check 
    include_deployment_checks=include_deployment_checks, 
   File "c:\Python27\lib\site-packages\django\core\management\base.py", line 361, in _run_checks 
    return checks.run_checks(**kwargs) 
   File "c:\Python27\lib\site-packages\django\core\checks\registry.py", line 81, in run_checks 
    new_errors = check(app_configs=app_configs) 
   File "c:\Python27\lib\site-packages\django\core\checks\urls.py", line 14, in check_url_config 
    return check_resolver(resolver) 
   File "c:\Python27\lib\site-packages\django\core\checks\urls.py", line 24, in check_resolver 
    for pattern in resolver.url_patterns: 
   File "c:\Python27\lib\site-packages\django\utils\functional.py", line 35, in __get__ 
    res = instance.__dict__[self.name] = self.func(instance) 
   File "c:\Python27\lib\site-packages\django\urls\resolvers.py", line 313, in url_patterns 
    patterns = getattr(self.urlconf_module, "urlpatterns", self.urlconf_module) 
   File "c:\Python27\lib\site-packages\django\utils\functional.py", line 35, in __get__ 
    res = instance.__dict__[self.name] = self.func(instance) 
   File "c:\Python27\lib\site-packages\django\urls\resolvers.py", line 306, in urlconf_module 
    return import_module(self.urlconf_name) 
   File "c:\Python27\lib\importlib\__init__.py", line 37, in import_module 
    __import__(name) 
   File "c:\Python27\Proj\mysite\mysite\urls.py", line 7, in <module> 
    url(r'^polls/', include('polls.urls')) 
   File "c:\Python27\lib\site-packages\django\conf\urls\__init__.py", line 50, in include 
    urlconf_module = import_module(urlconf_module) 
   File "c:\Python27\lib\importlib\__init__.py", line 37, in import_module 
    __import__(name) ImportError: No module named urls 

我在这里阅读了一些关于 SO 的答案，但他们认为这个错误是由错误的框架版本引起的，这不是我的情况。我的python版本是2.7和Djanog 1.10.1

我的 urls.py

from django.conf.urls import url, include 
 
 
from django.contrib import admin 
 
urlpatterns = [ 
    url(r'^polls/', include('polls.urls'))    ] 

谢谢。

编辑:

文件:polls/urls.py

from django.conf.urls import url 
 
from . import views 
 
urlpatterns = [ 
    url(r'^$', views.index, name='index'), 
]

感谢大家的评论。这是我的项目文件结构。

请您参考如下方法:

url(r'^polls/', include('polls.urls'))

这一行的作用是将 polls 应用程序文件夹的 urls.py 添加到您的 url，并将 polls/ 附加到所有人面前。

报错:

File "c:\Python27\Proj\mysite\mysite\urls.py", line 7, in <module> 
    url(r'^polls/', include('polls.urls')) 

错误表明它无法在 polls 文件夹中找到 urls.py，因此请确保它在那里。并正确配置。

还要确保以下几点:

• 您的应用投票在 settings.py 的 INSTALLED_APPS 中列出
• 确认__init__.py 文件在您的polls 应用程序文件夹中
