本文使用纯手工方式创建

设置镜像
npm config edit

在弹出的文档最后添加

electron_mirror=https://npm.taobao.org/mirrors/electron/
 
electron-builder-binaries_mirror=https://npm.taobao.org/mirrors/electron-builder-binaries/

yarn init
yarn add --dev electron
这一步需要保证github正常访问或者使用其他镜像
配置启动命令

//package.json
{
  "scripts": {
    "start": "electron ."
  }
}

package.json中调整入口文件为main.js

electron Helloworld_json

创建示例代码

依次创建下列文件
main.js

const { app, BrowserWindow } = require('electron')
const path = require('path')

function createWindow () {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  })

  win.loadFile('index.html')
}

app.whenReady().then(() => {
  createWindow()

  app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow()
    }
  })
})

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Hello World!</title>
    <meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline';" />
</head>
<body>
    <h1>Hello World!</h1>
    <p>
        We are using Node.js <span id="node-version"></span>,
        Chromium <span id="chrome-version"></span>,
        and Electron <span id="electron-version"></span>.
    </p>
    <script src="./preload.js"></script>

</body>
</html>

preload.js

window.addEventListener('DOMContentLoaded', () => {
  const replaceText = (selector, text) => {
    const element = document.getElementById(selector)
    if (element) element.innerText = text
  }

  for (const type of ['chrome', 'node', 'electron']) {
    replaceText(`${type}-version`, process.versions[type])
  }
})

运行
yarn start

效果如下

electron Helloworld_json_02

debian arm64打包树莓派系统

使用docker打包

拉取镜像
docker pull node:latest

运行node环境
docker run --name test -td docker.io/node

复制测试代码文件到node容器中
docker cp electrontest.zip 55ebb7b1f64f:/

进入node容器
docker exec -it 5faa0385f2e7 /bin/bash

调整package.json
