Question

我有一个项目说MyProject具有给定的目录结构，其中的应用程序安装在applications目录中。

.
├── myapp
│   ├── __init__.py
│   ├── __init__.pyc
│   ├── settings.py
│   ├── settings.pyc
│   ├── urls.py
│   ├── urls.pyc
│   ├── wsgi.py
│   └── wsgi.pyc
├── applications
│   └── polls
│       ├── admin.py
│       ├── apps.py
│       ├── __init__.py
│       ├── models.py
│       ├── tests.py
│       └── views.py
├── db.sqlite3
├── manage.py
└── wsgi
    ├── static
    │   └── keep.me
    └── wsgi.py

我的polls/apps.py内容

from __future__ import unicode_literals

from django.apps import AppConfig


class PollConfig(AppConfig):
    name = 'applications.polls'

和polls/__init__.py内容，

default_app_config='applications.polls.apps.PollConfig'

和设置中的INSTALLED_APPS

INSTALLED_APPS = [
    ......
    ......
    'applications.polls'
]

shell抛出ImportError: No module named polls

我该如何解决？

非常感谢你。

Answer 1

您需要在应用程序目录下创建一个__init__.py文件，以将其用作包/模块。

创建名为applications/__init__.py

的文件

Answer 2

另外，如果您的意思是django shell，或者您只想在python shell中使用您的应用，那么您必须先import django然后拨打django.setup()。
