TypeError: create_superuser() takes exactly 4 arguments (3 given)

[bw2]

Running

echo 'bla' | python -u manage.py createsuperuser --username test --email test

prints

Superuser creation skipped due to not running in a TTY. You can run manage.py createsuperuser in your project to create one manually.

but then also shows the following error message:
