ImportError: No module named app_name

问题

I am new to python and I have seen similar questions on SO but not able to figure out whats wrong with my Django app.

In settings.py I have added my app in dotted module form :

INSTALLED_APPS = (
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
        'mproject.blog',
)

and the Traceback :

D:\py pro\mproject>python manage.py runserver 9999
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
  execute_from_command_line(sys.argv)

    app = import_module(appname)
  File "C:\Python27\lib\site-packages\django\utils\importlib.py", line 40, in import_module
    __import__(name)
ImportError: No module named blog

In manage.py I have

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mproject.settings")

How to resolve this issue ?

回答1:

I don't think you need to use myproject.blog.

Just add blog to the installed apps. Thats enough.
