레일 서버를 실행할 때 오류가 발생했습니다.

Question

레일 블로그 앱에 선언적 권한을 설정하려고합니다. 필요한 모든 작업을 마친 후 레일을 사용하여 서버를 시작했습니다. 다음과 같은 오류가 발생했습니다.

rails s

내 블로그 앱은 blog 앱과 다소 비슷합니다.

이 문제를 해결하는 데 도움을주십시오. 감사. :) -

EDIT : authlogic 사용에 대한 의견이 있습니다. 여기에 같은 오류와 다른 GitHub의 페이지는 다음과 같습니다

https://github.com/binarylogic/authlogic/issues/316

이에 authlogic 보석 코드를 대체 :

gem "authlogic", :git => "git://github.com/binarylogic/authlogic.git"

이것은 레일 호환성 오류입니다. 오류와 함께이 GitHub의 페이지에서 볼 :
