/ bin / sh：1：[“ npm”，:：在docker-compose up上找不到 [英] /bin/sh: 1: [“npm”,: not found on docker-compose up

问题描述

我是docker的新手，正在尝试为节点应用程序创建容器。

I'm new to docker and trying to create a container for node apps.

我遵循了以下教程，但是在 docker-compose up 我总是遇到以下错误：

I followed these tutorial, but on docker-compose up I'm getting always these error:

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

这是我的Dockerfile：

Here is my 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：

and my docker-compose.yml:

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

有人知道如何解决这个错误？

Has anyone an idea how to fix this error?

推荐答案

在dockerfile中，引号有误：

You have the wrong quotes in your dockerfile:

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

与引号不匹配在您粘贴的示例中：

doesn't match the quotes in the example you pasted:

CMD ["npm", "start"]

再次检查您的Dockerfile以更正报价。

Double check your Dockerfile to correct your quotes.
