Docker Error

[NBHDQXT]

Docker 실행 시 오류
코덱의 유니코드가 utf-8이 아니라서 에러가 난다는 것 같은데, 이 코덱의 위치가 어딘지도 잘 모르겠어서 해결을 하지 못하는 상황이었습니다.
ㄴ 코덱의 유니코드가 아닌 backend의 .env파일을 utf-8로 바꾸니 해결되었습니다.

[시도]
"docker-compose.yml" 파일과
"docker-compose.dev.yml" 파일 모두에
" environment:
- PYTHONIOENCODING=utf-8" 라는 조건을 넣어보았으나 효과가 없었고,

backend 폴더의 "Dockerfile"에도
CMD 에 ["utf8"]의 요소를 추가하였으나 효과가 없었음.

[해결]
backend 폴더의 .env 파일을 메모장으로 utf-8로 바꾸어 저장 후
docker-compose up --build 명령어를 통해 재가동하니 해결된 것 같음.

오오 스스로 해결 했다니 멋져요! 👏
