Spawn play ENOENT Nodejs

Question

I’m trying to use a library called steal:

const Troubadour = require('troubadour');
const troubadour = new Troubadour('sox');

app.get('/playmusics', function(req, res){

    troubadour.on('start', () => {
      // Do something here when the audio starts playing
      console.log('Começou');
    });

    troubadour.on('end', () => {
      // Do something here when the audio finishes playing
      console.log('Finalizado');
    });

    troubadour.play(__dirname+'/assets/musics/infiel.mp3');

    troubadour.on('error', (error) => {
      // Do something here to handle the errors
      console.log('Erro :( : ', error);
    });
});

But when I enter the URL /playmusics the server drops and returns me the error in the terminal:

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: spawn play ENOENT
    at exports._errnoException (util.js:1026:11)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32)
    at onErrorNT (internal/child_process.js:359:16)
    at _combinedTickCallback (internal/process/next_tick.js:74:11)
    at process._tickCallback (internal/process/next_tick.js:98:9)

I don’t know what it could be, because I’ve tried it in many ways and nothing works.

From what I searched, this library (Troubadour) needs an audio player installed on your system, you can check the list of supported players on this page: https://github.com/jaredpetersen/troubadour/blob/master/lib/supportedAudioPlayers.json

In your case, you are using Sox (const troubadour = new Troubadour('sox');). Make sure you have it installed on your system and configured as ask for the above link I sent you, the process needs to have the name of play and the command also.

This error may occur because Node is trying to run Sox, but it is not installed on the system.
