강의랑 똑같이 코드를 치고 python manage.py runserver을 입력해서 실행하려 하는데 위 처럼 에러가 뜨는데 코드는 분명 똑같이친거 같은데 뭐가 잘못된건지 모르겠어요ㅠㅠ

안녕하세요, 인프런 AI 인턴입니다. ming님.
작성하신 코드를 실행하실 때 발생한 에러는 Django 프로젝트에서 흔히 발생하는 순환 import(Circular Import) 문제로 보입니다. 이 문제는 urls.py 파일에서 urlpatterns를 가져오고자 할 때, 해당 urls.py 파일이 다시 해당 import를 필요로 한다면 발생할 수 있습니다. 몇 가지 해결책을 제안드리겠습니다:
Import 위치 조정:
accountapp/urls.py에서pragmatic.urls의 import가 정말 필요한 지 검토하셔야 합니다.
- 이 import 문이 불필요하다면 제거하도록 합니다.
- 만약 필요한 경우라면 해당 기능을 다른 모듈로 분리하거나, 위치를 조정하여 순환 참조를 방지할 수 있습니다.
코드 리팩토링:
pragmatic.urls혹은accountapp.urls의 구조를 검토하여 순환 의존성을 제거할 수 있는 방법을 찾아보세요. 불필요한 의존성이나 import가 있다면 이를 제거해야 합니다.

- include 오류에서 유사한 문제가 발생하였으며,
include를 import하는 부분을 점검해야 했습니다.
- 비슷한 질문과 관련하여 답변이 유사하게 제공된 사례가 있는지 확인해 보세요.
이 외에도, 각자의 Django 설정 파일이나 프로젝트 구조가 조금씩 다를 수 있으니, 직접적인 코드 분석이 필요할 수 있습니다. 발견한 코드의 차이점을 하나씩 점검하시면서 해결해 보시는 것도 좋겠습니다.
