如何修复 Docker 中的 npm install 失败

Question

我正在尝试 dockerize 我的小型 reactjs 应用程序。

这是我的 Dockerfile

FROM node

WORKDIR /usr/src/app

COPY package.json .

COPY . .

EXPOSE 8080

RUN npm install // gives the error when executing this step
RUN npm install react-scripts@3.4.1 -g --silent

# start app
CMD ["npm", "start"]

这是我的 package.json

{
  "name": "cyberhr",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "3d-force-graph": "^1.60.11",
    "@tensorflow/tfjs": "^1.7.2",
    "@tensorflow/tfjs-tsne": "^0.2.0",
    "d3-dsv": "^1.2.0",
    "mdbreact": "4.25.3",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-force-graph": "^1.32.1",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.4.0",
    "tsne-js": "^1.0.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom"
  },
  "devDependencies": {
    "renamer": "^1.0.0",
    "rimraf": "^2.6.2"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

但它在npm install步骤中失败并给出以下错误

服务“前端”无法构建：命令“/bin/sh -c npm install”返回非零代码：244

这是详细的错误截图

有人可以帮帮我吗？

就我而言，我还必须复制package-lock.json到Dockerfile并且它有效。尽管跑步给我带来了漏洞，但我只需要这样做npm install。

尝试：

COPY package.json package-lock.json .
