本机菜单未显示OS X Electron

Question

我使用了电子快速启动程序来创建一个Electron应用程序，我希望显示的唯一本机菜单为“编辑”菜单，其中包含通常的可疑对象。

但是，在搜索并用尽了所有与Google相关的结果后，“电子菜单不起作用”后，我很茫然。

我当前的main.js文件：

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

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

app.setName('mathulator');

function createWindow () {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 900, height: 550})

  // and load the index.html of the app.
  mainWindow.loadURL(`file://${__dirname}/index.html`)

  // 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.

  const template = [
    {
        label: 'Mathulator',
        submenu: [
            {
                role: 'quit'
            }
        ]
    },
    {
      label: 'Edit',
      submenu: [
        {
          role: 'undo'
        },
        {
          role: 'redo'
        },
        {
          type: 'separator'
        },
        {
          role: 'cut'
        },
        {
          role: 'copy'
        },
        {
          role: 'paste'
        },
        {
          role: 'pasteandmatchstyle'
        },
        {
          role: 'delete'
        },
        {
          role: 'selectall'
        }
      ]
    }
   ]

  mainWindow.setMenu(Menu.buildFromTemplate(template))

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null
  })
}

// 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.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // On OS X it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', function () {
  // 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.
  if (mainWindow === null) {
    createWindow()
  }
})

我也用电子包装机包装了它，但无济于事。

我在main.js文件中运行该文件，这是主要过程，因此我应该在其中创建菜单。从文件中，我可以从网络上大量模糊或混乱的信息中收集到该文件。

我也尝试在render.js中做到这一点，我看到了建议。无济于事。它会显示为默认的电子快速启动菜单，或者仅显示一个以该应用程序命名的简单菜单，其中包含一个标记为“退出”的项目。

我可能做错了什么，或者可能从现有信息中误解了什么？

编辑：我实际上附加了错误的文件，Menu.setApplicationMenu()第一次尝试使用，像这样：

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

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

app.setName('mathulator');

function createWindow () {
    // Create the browser window.
    mainWindow = new BrowserWindow({width: 900, height: 550});

    // and load the index.html of the app.
    mainWindow.loadURL(`file://${__dirname}/index.html`);

    // Emitted when the window is closed.
    mainWindow.on('closed', function () {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        mainWindow = null;
    });
}

// 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.on('ready', createWindow);

// Quit when all windows are closed.
app.on('window-all-closed', function () {
    // On OS X it is common for applications and their menu bar
    // to stay active until the user quits explicitly with Cmd + Q
    if (process.platform !== 'darwin') {
        app.quit();
    }
})

app.on('activate', function () {
    // 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.
    if (mainWindow === null) {
        createWindow();
    }
})

const template = [
    {
        label: 'Mathulator',
        submenu: [
            {
                role: 'quit'
            }
        ]
    },
    {
        label: 'Edit',
        submenu: [
            {
                role: 'undo'
            },
            {
                role: 'redo'
            },
            {
                type: 'separator'
            },
            {
                role: 'cut'
            },
            {
                role: 'copy'
            },
            {
                role: 'paste'
            },
            {
                role: 'pasteandmatchstyle'
            },
            {
                role: 'delete'
            },
            {
                role: 'selectall'
            }
        ]
    }
];

Menu.setApplicationMenu(Menu.buildFromTemplate(template));

这里的问题BrowserWindow.setMenu()是仅在Windows和Linux上可用。在macOS上，您应该使用Menu.setApplicationMenu()。
