레일 프로젝트 헤 루크 : "죄송합니다.하지만 뭔가 잘못되었습니다."

Question

방금 ​​전 헤로큐 프로젝트를 추진했지만 "죄송하지만 뭔가 잘못되었습니다."- 시도 할 때 오류가 발생합니다. 웹 주소를 방문하십시오. 프로젝트를 업로드 한 직후에 heroku run rake db:migrate을 작성했습니다. 누군가 문제의 원인을 알고 있습니까?

Answer 1

에게 Heroku는 데이터베이스 PostgreSQL을 사용합니다. DATETIME is not a function postgres supports. 개발 환경에서 같은 버전의 postgresql 데이터베이스를 설정해야합니다. 어떤 OS를 사용하고 있습니까? 창문이 있다면, 나는 any answer for that이라고 썼다. (그것들 중 일부는 리눅스를 사용한다고해도 적용 가능하다.)
