When I try to play my Music Discord Bot it doesn't play music

Question

When I try to play my Music Discord Bot it doesn't play music. It uses ytdl-core and ffmpeg My code is:

const Discord = require('discord.js');
const bot = new Discord.Client

const ytdl = require("ytdl-core")


const token = 'API TOKEN'

const PREFIX = '?';

var version = '1.2';

var servers = {};

bot.on('ready', () =>{
    console.log('This bot is online!' + version);
})

bot.on('message', message => {

    let args = message.content.substring(PREFIX.length).split(" ");

    switch(args[0]){
        case 'play':

            function play(connection, message){
                var server = servers[message.guild.id];

                server.dispatcher = connection.play(ytdl(server.queue[0], {filter: "audioonly"}))

                server.queue.shift();

                server.dispatcher.on("end", function(){
                    if(server.queue[0]){
                        play(connection, message);
                    }else {
                        connection.disconnect();
                    }
                });



            }



            if(!args[1]){
                message.channel.send("You need to provide a link!")
                return;
            }

            if(!message.member.voice.channel){
               message.channel.send("You must be in a Voice Channel to play the bot!")
               return;
            }

            if(!servers[message.guild.id]) servers[message.guild.id] = {
                queue: []
            }

            var server = servers[message.guild.id];

            server.queue.push(args[1]);

            if(!message.guild.voice) message.member.voice.channel.join().then(function(connection){
                play(connection, message);
            })

        break;
    }



    });


    bot.login(token);

Whenever I try to play a song this error happens:

I'm getting very frustrated as the tutorial I'm watching is using a different version of everything.!! Please help.

Answer 1

Have you installed FFmpeg? Or ffmpeg-static?

Try doing npm i ffmpeg ffmpeg-static , it should update everything, let us know if it changes anything !

Also try to install npm i @discordjs/opus since it is required to play audio in Discord:)
