Why does Django swear when trying to start a local server?

Question

Django

I follow the instructions from the Hello Web App book.
I created a project, I start the server python manage.py runserver, it gives an error ImportError: No module named core.management.
Fixed by replacing the first line in my project's manage.py with

#!/Users/тут_имя_учетной_записи/Django/myhellowebapp/venv/bin/python

and re-activated venv. Did not help.
I tried changing the path to

#!/Users/тут_имя_учетной_записи/Library/Python/2.7/python

, the same. Here is what he writes:
