The newly created Django project will run directly after entering

python manage.py runserver

The mistakes are as follows:

user@UserdeMacBook-Pro djangoProject % python manage.py runserver
  File "manage.py", line 17
    ) from exc
         ^
SyntaxError: invalid syntax

I feel a little puzzled. Later, I found that there was a problem with the specification of the python version. I should specify the python 3 version

python3 manage.py runserver

That’s it.
