안녕하세요 점프투플라스크를 보면서 수많은 오류와 부딪히며 여기까지 달려왔습니다.
그런데 이번 오류는 어떻게 해결해야할지 모르겠어서 질문을 드립니다.

guniconr을 실행하면 아래와 같이 메세지가 발생합니다.
(flaskproject) ubuntu@ip-172-26-6-38:~/projects/myproject$ gunicorn --bind 0:5000 "pybo:create_app()"

production.py의 경로를 찾지 못하는 것 같은데,
어떤 부분이 문제일까요?

default.py에서
import os
BASE_DIR = os.path.dirname(os.path.dirname(file))

이거랑 관련있을 것 같아서 수정해보았는데 이걸 수정하면 로컬서버가 작동을 안하고요
책에 있는 그대로 하면 로컬서버에서는 잘 작동하는데 gunicorn은 실행이 안됩니다.

도와주셔서 미리 감사드립니다 ㅠㅠ
