Django 1.9 ImportError：外壳上没有名为“ appname”的模块

Question

I have a project say MyProject with the given directory structure, where the apps are installed in the applications directory.

.
├── 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

My polls/apps.py content is

from __future__ import unicode_literals

from django.apps import AppConfig


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

and the polls/__init__.py content,

default_app_config='applications.polls.apps.PollConfig'

and the INSTALLED_APPS in settings,

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

the shell throws ImportError: No module named polls

How do I fix it?

thank you so much.

Answer 1

You need to create a __init__.py file under applications directory to use it as a package/ module.

create a file named applications/__init__.py

Answer 2

另外，如果您的意思是django shell或者如果您只是想从python shell中使用您的应用程序，则必须首先import django然后调用django.setup() 。
