electron菜单不显示问题

买下一张永久车票，登上一列永无终点的火车。——马尔克斯的《百年孤独》

解决代码如下：

const {app, BrowserWindow, Menu} = require('electron');
const path = require('node:path');

// Handle creating/removing shortcuts on Windows when installing/uninstalling.
if (require('electron-squirrel-startup')) {
    app.quit();
}

console.log("app name", app.getName())

const template = [
    {
        label: '文件(F)',
        role: 'services',
        submenu: [
            {
                label: '',
            }
        ]
    }
]

const menu = Menu.buildFromTemplate(template)
Menu.setApplicationMenu(menu)

const createWindow = () => {
    // Create the browser window.
    const mainWindow = new BrowserWindow({
        width: 1200,
        height: 600,
        webPreferences: {
            preload: path.join(__dirname, 'preload.js'),
        },
    });

    // and load the index.html of the app.
    mainWindow.loadFile(path.join(__dirname, 'index.html'));

    // Open the DevTools.
    // mainWindow.webContents.openDevTools();
};

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.whenReady().then(() => {
    createWindow();

    // On OS X it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
    app.on('activate', () => {
        if (BrowserWindow.getAllWindows().length === 0) {
            createWindow();
        }
    });
});

// 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.
app.on('window-all-closed', () => {
    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 import them here.

主要是添加了一个label为空的submenu
