docker-compose fails to start with npm ERR! enoent ENOENT: no such file or directory, open '/usr/src/app/package.json'

I built an image from a docker file to run node and copy in a simple node express app which works perfectly. The image builds I can run a container and bash in and the local files are copied. When I use this image in a docker-compose file along with a mongo image the containers build but the node container fails to run with an error is the package.json is missing.

The error returned is

report-node exited with code 254
report-node | npm ERR! path /usr/src/app/package.json
report-node | npm ERR! code ENOENT
report-node | npm ERR! errno -2
report-node | npm ERR! syscall open
report-node | npm ERR! enoent ENOENT: no such file or directory, open '/usr/src/app/package.json'
report-node | npm ERR! enoent This is related to npm not being able to find a file.

report-node | npm ERR!     /root/.npm/_logs/2019-02-26T10_55_05_562Z-debug.log
report-node exited with code 254

dockerfile

FROM node
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 4000
CMD [ "npm", "run", "dev"  ]

Docker-compose.yml looks like

version: '3'
services:
  app:
    image: gosmith/node10:latest
    container_name: report-node
    restart: always
    volumes:
      - ./:/usr/src/app
    working_dir: /usr/src/app
    depends_on:
      - mongo
    environment:
      NODE_ENV: development
    ports:
      - 4000:4000
      - 8080:8080
    command: npm run dev && npm run serve
  mongo:
    container_name: mongo
    image: mongo
    expose:
      - 27017
    ports:
      - 27037:27017
    volumes:
      - ./data:/data/db

How has the package.json gone missing? Thanks for your help!

I also face same problem on Ubuntu 20.04 and docker-desktop 20.10.16 I changes following:

Before Solving Problem:

Dockerfile contain

WORKDIR /app

And docker-compose.yaml file contains:

services:
   backend:
     volumes:
        - ./:/app

After Solving Problem my files look like

Dockerfile

WORKDIR /app/project

docker-compose.yaml

services:
  backend:
    volumes:
      - ./:/app/project

I had the same problem. In your case do it like this: In volumes changes this - ./:/usr/src/app for this

volumes:
      - ./:/app

the /app name is this:

services:
   app:

When your docker-compose.yml says

volumes:
  - ./:/usr/src/app

it hides everything that gets done in the Dockerfile and replaces it with the current directory. If your current directory doesn't have the package.json file (maybe you moved everything Docker-related into a subdirectory) it will cause the error you see.

Personally I would just remove these two lines, develop my application locally (without Docker, using the per-project node_modules directory for isolation), and only build the Docker image when I'm actually ready to deploy it.
