title: /bin/sh: 1: [“npm”,: not found on docker-compose up
body: <p>I'm new to docker and trying to create a container for node apps.</p>
  
  <p>I followed these <a href="https://medium.com/statuscode/dockerising-a-node-js-and-mongodb-app-d22047e2806f" rel="noreferrer">tutorial</a>, but on <code>docker-compose up</code> I'm getting always these error:</p>
  
  <pre><code>Creating app ... done
  Attaching to app
  app    | /bin/sh: 1: [“npm”,: not found
  app exited with code 127
  </code></pre>
  
  <p>Here is my Dockerfile:</p>
  
  <pre><code>FROM node:latest
  RUN mkdir -p /usr/src/app
  WORKDIR /usr/src/app
  COPY package.json /usr/src/app/
  COPY package-lock.json /usr/src/app/
  RUN npm install
  COPY . /usr/src/app
  EXPOSE 3000
  CMD ["npm", "start"]
  </code></pre>
  
  <p>and my docker-compose.yml:</p>
  
  <pre><code>version: "2"
  services:
    app:
      container_name: app
      restart: always
      build: .
      ports:
        - "3000:3000"
  </code></pre>
  
  <p>Has anyone an idea how to fix this error? </p>
