我有一个角电子应用程序，工作完美的罚款（开发环境）之前捆绑它与电子建设者。捆绑后，安装和打开它，一个得到了一个白色的屏幕没有错误！
下面是我的项目的package.json文件

这是我的项目的electron.prod.js文件

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

// 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 win;

const createWindow = () => {
    // Create the browser window.
    win = new BrowserWindow({
        width: 800,
        height: 600,
        icon: path.join(__dirname, 'favicon.ico'),
    });

    // and load the index.html of the app.
    win.loadURL(url.format({
        pathname: path.join(__dirname, 'index.html'),
        protocol: 'file:',
        slashes: true
    }));
    win.webContents.openDevTools();
    // Emitted when the window is closed.
    win.on('closed', () => {
        // 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.
        win = 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', () => {
    // On macOS 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', () => {
    // On macOS 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 (win === null) {
        createWindow();
    }
});

我真的很困惑！我相信我所有的代码都是正确的，可能我忘记了什么
有什么想法吗！！
