如何用Node.js/Electron获取并操作Windows虚拟桌面信息？

针对你遇到的node-gyp编译问题，推荐两种无需复杂编译的实现方案，均适配Windows 10+系统：

方案一：使用预编译npm包（推荐） #

virtual-desktop-accessor是一款预编译的第三方包，无需node-gyp编译，直接调用Windows原生虚拟桌面API，能完美实现你的需求。

步骤1：安装依赖 #

npm install virtual-desktop-accessor

步骤2：修改main.js实现完整功能 #

const { app, Tray, Menu } = require("electron");
const vda = require("virtual-desktop-accessor");

let tray = null;
let currentDesktop = null;
let allDesktops = [];

// 更新托盘提示和右键菜单
function updateUI() {
  const menuItems = allDesktops.map(desktop => ({
    label: desktop.name,
    type: "radio",
    checked: desktop.id === currentDesktop.id,
    click: () => vda.switchToVirtualDesktop(desktop.id)
  }));
  menuItems.push({ type: "separator" });
  menuItems.push({ label: "Exit", role: "quit" });

  const contextMenu = Menu.buildFromTemplate(menuItems);
  tray.setToolTip(currentDesktop.name);
  tray.setContextMenu(contextMenu);
}

app.whenReady().then(async () => {
  tray = new Tray("./assets/icons/monitor.ico");

  // 初始化获取桌面信息
  allDesktops = await vda.getAllVirtualDesktops();
  currentDesktop = await vda.getCurrentVirtualDesktop();
  updateUI();

  // 监听虚拟桌面切换事件
  vda.onVirtualDesktopChanged(async () => {
    currentDesktop = await vda.getCurrentVirtualDesktop();
    // 刷新桌面列表（适配用户增删/重命名桌面）
    allDesktops = await vda.getAllVirtualDesktops();
    updateUI();
  });
});

方案二：无依赖调用PowerShell脚本 #

如果不想引入第三方包，可以通过child_process调用PowerShell脚本直接操作Windows COM接口，完全避免npm包的编译问题。

核心功能实现代码 #

const { app, Tray, Menu } = require("electron");
const { exec } = require("child_process");

let tray = null;

// 获取所有虚拟桌面信息（ID+名称）
function getAllDesktops() {
  return new Promise((resolve, reject) => {
    const psScript = `
