node.js – / bin / sh：1：[“npm”,：在docker上找不到[复制]

我是docker的新手,并尝试为节点应用程序创建容器.

我跟着这些tutorial,但是在docker-compose上我总是得到这些错误：

CreaTing app ... done
Attaching to app
app    | /bin/sh: 1: [“npm”,: not found
app exited with code 127

这是我的Dockerfile：

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"]

和我的docker-compose.yml：

version: "2"
services:
  app:
    container_name: app
    restart: always
    build: .
    ports:
      - "3000:3000"

有谁知道如何解决这个错误？

app    | /bin/sh: 1: [“npm”,: not found

CMD ["npm","start"]
