使用virtualenv在Django中创建了新项目,并且运行良好,但是当我尝试使用“ startapp”创建新应用并再次通过命令运行项目时: python3.6 advertising / manage.py runserver本地主机:8000
then throw error :

ModuleNotFoundError: No module named 'core'
注意:我已经在安装了setting.py的应用中添加了该应用。
请帮助我解决这个问题。

添加一些INSTALLED_APPS的代码。您只是说django在mysite文件夹中添加了一个应用程序“核心”,而django无法找到它。
1)删除mysite.core,然后运行迁移。
2)在mysite中创建一个应用核心。并创建一个应用意味着它应该具有app.py文件。它包含
或者您在这样的INSTALLED_APPS中提到了您的应用
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'mysite.core',
]
然后您的目录应该是这样
mysite/
├── core
│ ├── __init__.py
│ └── views.py
└── __init__.py

仅当您创建应用并创建网址但没有在urls.py文件中引用的views.py文件中创建函数时,才会发生此类错误。解决方案如下:
python manage.py runserver
python3.6 manage.py运行服务器
