[NodeJS, GCP] 반영시 오류 cannot find module /srv/server.js, cannot find module ./bin/www

로컬호스트에서 테스트하거나 EC2에서 작업해도 문제가 없는 소스였다. GCP AppEngine에 올리려고 하자 이런 오류를 만났다.

package.json을 확인해보자

적어도 아래 라인이 존재해야한다.

"main": "app.js"

 

그리고 나같은 경우에는 아래 쿼리가 문제였다. 여기가 /bin/www로 되어 있었다.

"scripts": {
    "start": "node app.js"
},
