Javascript 网页包+；Discord.js+；电子

我在构建网页包时遇到了一个问题

未初始化Discord客户端

这是我在电子方面的第一个应用。请帮忙

错误：未捕获类型错误：i（…）。客户端不是Web包文件中的构造函数

如果我请求帮助，我会很高兴得到一个好的答案。下面我将提供所有文件的代码。

main.js

const path = require('path');
const url = require('url');
const {app,BrowserWindow} = require('electron');
const {sendMessage,isValidForm} = require('./back.js');


let win;

function createWindow() {
    win = new BrowserWindow({
        width: 1200,
        height : 800,
        icon : __dirname + "/img/icon.png"
    });

    win.loadURL(url.format({
        pathname: path.join(__dirname,"/html/index.html"),
        protocol: 'file:',
        slashes: true
    }));

    win.webContents.openDevTools();

    win.on('closed', () => {
        win = null;
    });
}

app.on('ready', createWindow);

app.on('window-all-closed',() => {
    app.quit();
});
