  • FFMPEG not found error while attempting to implement ffmpeg into discord bot

    17 février 2020, par Ravenr_

    While implementing a music feature into my node.js discord.js discord bot, I got an error claiming that it cant find FFMPEG. I reinstalled ffmpeg 3 times to no avail.

    This is the full error

    This is the code

    const ytdl = require("ytdl-core");
    
module.exports = {
    
    name: 'play',
    
    description: 'initiates music methods of the bot',
    
    execute(msg, args){
    
        var servers = {};
    

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

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

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

    

    
        }
    
        if(!args[1]) return msg.channel.send("you need to provide a link");
    
        if(!msg.member.voiceChannel) return msg.channel.send("You must be in a voice channel to use this feature");
    
        if(!servers[msg.guild.id]) servers[msg.guild.id] = {
    
            queue: []
    
        }
    
        var server = servers[msg.guild.id];
    
        server.queue.push(args[1]);
    
        if(!msg.guild.voiceConnection) msg.member.voiceChannel.join().then(function(connection){
    
            play(connection, msg);
    
        })
    
    }
    
}

    I have no idea what the issue is. I am using heroku to deploy if that matters at all.
