나는 레일 튜토리얼 (2.2 절)에있는 Hartl 루비를 통해 일하고 있어요, 나는 문제가 데이터베이스를 마이그레이션하는 데 문제가 있습니다. 모든 작업이 될 듯하고 나는 레일 비계 사용자 이름을 생성 실행 : 문자열 이메일 : 문자열이 그 후 나는 번들 간부 갈퀴 DB를 실행하려고 : 마이그레이션 및 오류 메시지가 아래에있어 :

나는 이전 커밋하고 다시 모든 것을 실행하지만 난 얻을 같은 오류 메시지가 다시가는 시도했습니다. 나는이와 그 캔 도움말을 추가하는 것이 더 이상 파일이 있습니까?

해결법

1. ==============================

   1.난 그냥뿐만 아니라이 다 퉜다. 이 Arel :: 노드 :: BindParam.new에 매개 변수를 전달 액티브의 4.2.0.beta4 때문이다. Arel 6.0.0 단지 오늘 발표했다. 이 버전에서는 BindParam 그것의 initalizer의 모든 매개 변수를 허용하지 않습니다.

   난 그냥뿐만 아니라이 다 퉜다. 이 Arel :: 노드 :: BindParam.new에 매개 변수를 전달 액티브의 4.2.0.beta4 때문이다. Arel 6.0.0 단지 오늘 발표했다. 이 버전에서는 BindParam 그것의 initalizer의 모든 매개 변수를 허용하지 않습니다.

   액티브는 이미 마스터 분기에이 문제를 해결했다. beta5가 해제 될 때까지 당신은 보석 'arel', '6.0.0.beta2'에 Gemfile을 고정해야합니다.

2. ==============================

   2.gemfile 변화의 상기 용액.

   gemfile 변화의 상기 용액.

    gem 'arel', '6.0.0.beta2'
   

   나는 오류 메시지가 아래에 있어요.

   You have requested:arel = 6.0.0.beta2
   
   The bundle currently has arel locked at 6.0.0.
   Try running `bundle update arel`
   

   후

   bundle update arel    
   

   그것은 일

3. ==============================

   3.나는 이것을 해결했습니다

   나는 이것을 해결했습니다

   rake db:reset
   

   그 후

   rake db:migrate
   

   했다.
