안녕하세요, django를 공부하는 중에 해결이 안되는 부분이 있어서 여쭤봅니다!

점프 투 장고 에서 python manage.py collectstatic, 명령어를 이용해 django 웹서비스에 admin으로 접속할 때 CSS파일을 가져올 수 있게 하려고 하면... 예외가 발생하는데요,
일단 전 현재 Ubuntu 20.04.4 버전을 사용하고 있고 '점프 투 장고' 책에서 사용한 Nginx와 Gunicorn을 사용하고있습니다.

에러가 발생하는 부분을 살펴보자면,

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

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

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

구글링도 해보고 STACKOVERFLOW도 뒤져봤는데요, STATIC_ROOT가 제대로 설정되어있지 않을때 발생하는 예외라고 하더군요,

일단 추측으로는 STATIC ROOT를 설정해도 경로를 제대로 인식하지 못하고 있는 것이라 생각하고 이것 저것 바꿔보고 있는데, 신통치는 않더군요.

    location / {
        include proxy_params;
        proxy_pass http://unix:/tmp/gunicorn.sock;
    }
}

일단 구글링해서 시도해본 방법으로는:

내가 해본 방법

STATIC_ROOT 하고 STATIC_URL 변수를 prod.py에 지정해주기,
STATIC_ROOT 하고 STATIC_URL 변수를 base.py에 지정해주기,

등인데요, import os를 통해서 변수를 지정하는 방법도 있고 이것저것 해봤는데 django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path. 는 여전히 절 괴롭히더군요...

이제는 STATIC_ROOT 또는 STATIC_URL, STATICFILES_DIR 변수를 정확히 어디에 집어넣어야 해결될지 감이 잡히지 않습니다...
혹시 비슷한 경우를 겪으신 분이 있을까요?
