SyntaxError: invalid syntax

Reproduce the reported pyinstaller command with a Django project whose settings.py has a syntax error. Start with hooks/hook-django.py and utils/hooks/django.py, then follow the django_import_finder.py evaluation path shown in the traceback. Done means the failure is handled with an actionable result rather than the current crash.
