NodeJs 응용 프로그램을 배포 할 때의 로그의 Heroku bcrypt 오류 이해

Question

node.com 응용 프로그램을 Heroku에 배포하려고합니다. 그것은 로컬 완벽하게 잘 작동하지만 내가 그것을 배포 할 때 나는이 점점 계속 :

I 설치하고 NPM 다시 bcrypt 설치 NPM 수행했지만 오류가 지속됩니다. 로그를 이해 한 결과 오류가 bcrypt와 관련이 있다는 것이 확실하다고 생각하십니까?

당신은 bcrypt 라이브러리의 순수한 JS 버전을 사용할 수 있습니다

여기 내 package.json 파일입니다. 이

https://github.com/dcodeIO/bcrypt.js 

이 나던 같은 뭔가 네이티브 종속성이 완벽하게 작동합니다. heroku와 다른 클라우드 플랫폼에 네이티브 종속성이있는 응용 프로그램을 배포하는 데 많은 어려움을 겪었으며 bcrypt와 같은 일부 라이브러리를 순수 js 버전으로 교체해야했습니다.
