ImportError：没有名为books.apps的模块（Django）

Question

I would like to use Django to create an app but got an error

"ImportError: No module named books.apps" after running:

python manage.py startapp books

Error message:

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/Library/Python/2.7/site-packages/Django-1.9-py2.7.egg/django/core/management/__init__.py", line 350, in execute_from_command_line

    __import__(name)
ImportError: No module named books.apps

Any idea what went wrong? Thanks!

You must first start a project before trying to start an app. First run:

python manage.py startproject mysite

and replace "mysite" with what you want to call your project. Then run:

python manage.py startapp books

See the docs here .
