smtp error running db : migrate in rails

Question

내 사용자 모델에 몇 가지 변경 사항을 적용하려고하고 있으며 마이그레이션을 실행할 때 sqlite가 테이블이 이미 존재 함을 나타내는 오류가 발생했습니다. 그런 다음 다음 단계를 수행했습니다. rake db : drop, rake db : rake db : migrate. 마이그레이션을 실행했을 때 다음과 같은 오류가 발생했습니다. 나는 이것으로 어디서부터 시작해야할지 모르겠습니다. 나는 메일 문제로 나를 가리키고있는 것 같지만 조금 혼란스러워! 내가 만든 모델은 다음과 같다. 레일즈 g 모델 purchase subscription_id : integer buyer_id : integer. 두 가지 문제가 관련되어 있습니까?
