레일 4 응용 프로그램에 Heroku, 작동하지만 로그에 오류

Question

응용 프로그램이 작동하는 것처럼 보이지만 내 로그에서 이러한 오류가 발생합니다. 이 문제는 각 페이지로드시 "/faicon.ico", "/assets/application-34baf7d108c7408a8c110454dc57e8f6.js"및 "/assets/application-e6b66fbbea8acd5eddb9fada1fa91c36.css"에 대한 로그에 표시됩니다.

또한이 문제는 heroku에서만 발생하지 않습니다.

그리고 루비가 1.9.1이라고해도 "heroku run ruby ​​-v"로 확인하고 "ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64- 그런 다음, 로컬 자산을 컴파일 할 수 있습니다 리눅스] "

Answer 1

내가 오류를 제거, 당신의 솔루션에 대한 대안으로 내 설정/enviroments에에/production.rb

- config.assets.compile = false 
+ config.assets.compile = true 

Answer 2

을 이런 짓을 영웅에게 보내십시오.

$ rake assets:precompile 
$ git add -A 
$ git commit -m 'compiled assets' 
$ git push heroku master 

이 작업은 CI 단계의 일부로 수행합니다.
