Python Django 1.8 AttributeError:模块没有属性'；网址'；

我正在做一个显示“hello world！”的练习，但当我打开网站时，django给出了一个例外。我该如何解决这个问题

例外情况是：

AttributeError at /
module 'apps.release_news' has no attribute 'urls'
Request Method: GET
Request URL:    http://127.0.0.1:8000/
Django Version: 1.8.7

目录DemoGuitarProject中的My URL.py是：

代码来自DemoGuitarProject/url.py

from apps import release_news

from apps.release_news import urls as release_news_urls

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^release_news/', include(release_news_urls)), 
]

读取文件

apps/release\u news/\uuuuuu init\uuuuuuu.py

from apps import release_news

from apps.release_news import urls as release_news_urls

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^release_news/', include(release_news_urls)), 
]

我猜这个文件是空的。添加到此文件：

from apps.release_news import urls

或者更改

DemoGuitarProject/url.py

from apps import release_news

from apps.release_news import urls as release_news_urls

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^release_news/', include(release_news_urls)), 
]

@Sayse我刚刚尝试删除密钥，但仍然无法正常工作，因为给出了一个异常：raise INPROPERLYCONFIGURED（“密钥设置不能为空”）@KamiWan，@Sayse希望您从发布的代码中删除

密钥，它可能被利用。您不应该在可公开访问的代码中包含这样的敏感数据。@mic4ael，@Sayse我已经这样做了。感谢您提醒我。虽然您已从问题中删除了密钥，但它仍会显示在编辑历史记录中。在应用程序中更改密钥也是一个好主意。不用担心，我已经删除了我的评论，这样人们在编辑历史记录中搜索的时间就少了。至少，我鼓励以上所有人也这样做。这也是所有噪音远离你的实际问题你的猜测是正确的，你的建议真的工作！我仍然不明白为什么使用“from apps import release_news”语句不能让django在release_news目录中找到url.py文件？理解导入机制的最佳地方：
