Node Js not running in Docker Environment Pin

Question

My NodeJS is not running in Docker environment. Specifically, my express module is not loaded within the Docker container.

This is my setup so far:

server.js

var express = require('express')

var app = express();

app.get('/', function (req, res) {
    res.end('Hello world');
})

var server = app.listen(9005, function () {
    var host = server.address().address
    var port = server.address().port

    console.log("Example app listening at http://%s:%s", host, port)
})

Dockerfile

 FROM stefanscherer/node-windows:7.6.0-nano

 # Create app directory
 RUN mkdir -p /app
 WORKDIR /app

 # Install app dependencies
 COPY package.json /app/
 RUN npm install

 # Bundle app source
 COPY . /app

CMD ["node","server.js"]
EXPOSE 9005

您确定在 package.json 的依赖项部分中包含了 express 吗？
