error running simple electron program

a few days ago I started to learn about electron and I started to make a small project to download youtube videos to test the things around. Here is the code

main.js:

const electron = require(‘electron’);
const path = require(‘path’);
const url = require(‘url’);
const youtubedl = require(‘youtube-dl’);

const {app, BrowserWindow, Menu, ipcMain} = electron;

let mainWindow;

app.on(‘ready’, function()
{
mainWindow = new BrowserWindow({});
mainWindow.loadURL(url.format({
pathname: path.join(__dirname, ‘index.html’),
protocol: ‘file:’,
slashes:true
}));
mainWindow.on(‘closed’, function(){
app.quit();
});

const mainMenu = Menu.buildFromTemplate(mainMenuTemplate);
Menu.setApplicationMenu(mainMenu);
});

exports.getUrlInformation=(arg)=>
{
var url = arg;
var options = [];
youtubedl.getInfo(url, options, function(err, urlInformation)
{
if (err) throw err;

mainWindow.webContents.send('UrlInformation', urlInformation);
});
}

index.js:

var {ipcRenderer, remote} = require(‘electron’);
var mainProcess = remote.require("./main.js");

class YouTubeDownloaderForm extends React.Component
{
constructor(props)
{
super(props);
this.state = {url: ‘’};
this.handleAddClick = this.handleAddClick.bind(this);
}
handleAddClick(event)
{
mainProcess.getUrlInformation(this.state.url);
}

I looked into devtool console and this is the error that shows up. Does this look like a installation error?

I fixed the npmjs.com/package/youtube-dl issue by download the latest youtube-dl exe from https://youtube-dl.org/downloads/latest/youtube-dl.exe, then putting it in node_modules\youtube-dl\bin
