ImportError：没有名为'posts.urls'的模块

Question

我是Django的新手，并开始使用https://docs.djangoproject.com/en/2.0/intro/tutorial01/的django官方教程制作我的第一个Django应用程序。

我已经安装了python3.5.2和pip 9.0.1，使用Ubuntu 16.04，Django版本是2.0。

我的urls.py文件包含以下代码

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

urlpatterns = [
path('posts/', include('posts.urls')),
path('admin/', admin.site.urls),
] 

如果有什么可以帮助我解决这个问题。下面是我在运行命令后得到的错误 - python manage.py runserver

这是我得到的错误

如果有什么可以帮助我的。我已经尝试过在互联网上存在的所有其他解决方案。

/ var / www / html / django-projects / djangoblog /必须是您的项目根目录。如果您使用像PyCharm这样的IDE，请右键单击“djangoblog” - 文件夹 - >标记目录为 - >源根

如果你使用shell来运行Django：

cd /var/www/html/django-projects/djangoblog/
./manage.py runserver

希望这对你有用。
