Python manage.py collectstatic TypeError: требуется целое число (получил тип str)

Question

Я работаю с Django версии 2.2.Когда я запускаю команду python manage.py collectstatic

, я получаю следующий журнал на терминале bash.

You have requested to collect static files at the destination
location as specified in your settings:

    /home/djapp/poorface/staticfiles

This will overwrite existing files!
Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel: yes

Я изменил разрешения статических файлов на -rwxrwxrwx.Тогда также нет никаких изменений в выходе.

manage.py выглядит как

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Poorface.settings")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
