/ bin/sh:1:["npm",:在docker-compose上找不到

Question

我是docker的新手,并尝试为节点应用程序创建容器.

我按照这些教程,但docker-compose up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？

您的dockerfile中有错误的引号:

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

与您粘贴的示例中的引号不匹配:

CMD ["npm", "start"]

仔细检查您的Dockerfile以更正您的报价.
