vue3使用Electron打包成exe的方法与打包报错解决

npm install electron --save-dev
npm install electron-builder --save-dev

// main.js

// Modules to control application life and create native browser window
const { app, BrowserWindow,Menu } = require('electron')

const createWindow = () => {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true, // 启用 Node.js 集成
      contextIsolation: false, // 禁用上下文隔离（Node.js 集成的一个选项）
      webSecurity: false, // 禁用同源策略
      contextIsolation: false,
      session: {
        cookies: true // 这行确保启用了cookie
      }

    },
    icon: 'build/.icon-ico/icon.ico'//这里是自动生成的图标，默认情况下不需要改

  })

  // and load the index.html of the app.
  mainWindow.loadFile('./dist/index.html')//如果要本地化，这样写，如果写远程的，那这里就是请求的域名
  //隐藏顶部菜单
  // mainWindow.setMenu(null);
  // Open the DevTools.
  // Open the DevTools.
  //mainWindow.webContents.openDevTools()
  mainWindow.maximize();//默认最大化
}
//设置中文菜单，默认是英文的
const createMenu = () => {

      submenu: [
        {

  const menu = Menu.buildFromTemplate(template);

}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.

    // dock icon is clicked and there are no other windows open.

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.

  if (process.platform !== 'darwin') app.quit()
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
