서버 모듈, 라이브러리 인스톨 문제

Question

안녕하세요! 이번에 ssh를 이용해 외부 서버를 이용해 배포하려고 합니다. 테스트를 하기 위해서 강사님의 django-with-react-rev5 파일을 깃 허브에서 클론하였고 (물론 제 파일로도 시도해보았습니다.) - > https://github.com/askcompany-kr/django-with-react-rev5.git 모듈과 라이브러리를 인스톨 하기 위해서 python install -r requirements 를 통해 인스톨 했습니다. backend 인스톨 받아졌는데 System check identified no issues (0 silenced).

프로젝트 구동을 위해 환경변수 지정이 필요하실 것입니다. 프로젝트 settings 코드를 살펴보시면 환경변수를 참조하는 코드가 있습니다. 환경변수 지정에 대해서는 배포 에피소드를 참고해보세요. :-) 장고가 바라보는 데이터베이스는 DATABASE_URL 환경변수를 참조하며, 해당 환경변수가 없을 경우 sqlite3 데이터베이스를 활용하려 시도합니다.
