ImproperlyConfigured : settings.DATABASES 오류가 부적절하게 구성되었습니다. ENGINE 값

Question

을 적절히 설정하십시오 : settings.DATABASES가 잘못 구성되었습니다. ENGINE 값을 입력하십시오.

지난 3 일 동안이 문제로 고통 받고 있습니다.

다른 블로그 (심지어 stackoverflow)와 솔루션에서 중복 티켓의 음조를 보았지만 그 중 아무 것도 양식을 만들지 못했습니다.

마지막으로 나는 settings.py에서 무엇이 잘못되었는지 물어볼 필요가 없으며 새로운 AWS 인스턴스에서 django 앱을 변경 한 후에도 문제가 발생하지 않는 이유는 무엇입니까?

내 setting.py :

최근 내 프로젝트 장고 1.4에서 실행했지만, 난이 때문에 일부 smartbyte 인코딩 오류로 1.5으로 업데이트되었습니다. 그 문제가 시작된 후 나는 장고 1.4로 다운 그레이드했다. 다운 그레이드가 끝나지 않았어도 내 전체 프로젝트를 새로운 AWS 인스턴스 (우분투 14.04)로 옮겼습니다.

settings.configure() 

을 사용하고하면 privious 설정을 오버라이드 (override) 할 것으로 보인다. 이것은 귀하의 문제의 열쇠가되어야합니다.

실제로 인수없이 configure()를 호출하면 django는 일반적으로 db 엔진이 정의되지 않은 기본 설정을 사용하므로 오류가 발생합니다.
