개발 환경에서는 문제없이 움직이고 있던 앱이 만나고 배포했을 때 충돌하면 정신적으로 괜찮을 것입니다.

정직하고 힘들다.

이번에는 Rails5의 앱을 Heroku에 배포했을 때 충돌을 일으켰기 때문에 그 때 취한 행동을 메모로 남겨 둡니다.

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

이 에러문 자체를 검색해, 여러가지 에러시 대응의 기사를 읽어 가면,何にしろログを見なっせ (쓰고 있다)라는 것이므로,$ heroku logs 를 두드렸습니다.

이 기사 은 매우 도움이 되었습니다.

마음이 꺾인 것

부러졌습니다.

힘들었기 때문에 오류 문장의 끝에있었습니다.heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/"에러 코드가 기재되어 있고 나중에 구글 선생님이 어떻게든 해줄 것이라고 뇌사로 검색했습니다.

결과적으로 알게 된 것은,

오류 문장

힘든! ! !

눈에서 흘러넘치는 국물로 퍼지는 화면을 읽어 진행한 곳, 다음 부분에 눈이 머무른다고 해도 초반의 분.

2020-02-19T13:24:19.870924+00:00 app[web.1]: LoadError: No such file to load -- URI.rb

정중하게 ！까지 붙여 있다.

여기서 핑과 와서, 그러고 보니 그물에서 다음 코드를 복사했을 때,

example_controller.rb

require 'net/https'
require 'uri'        # 'URI'と記載していた

에서 실행 한 결과, uriなんてねえよバーカ！'uri' => 'URI' 라고 정정한 것을 기억했습니다.

오, 그래?

그 후, 올바르게 require 'uri' 라고 정정하면 무사동해 주었습니다.

오류 문장을 읽자 (결론)

마음이 부러지면 숨을 쉬는 것도 잊지 마십시오.
