Could not find an Opus module

[GuillaumeNachury]

I'm trying to get my bot working on linux (Linux vpsxxxx.ovh.net 3.16.0-7-amd64 #1 SMP Debian 3.16.59-1 (2018-10-03) x86_64 GNU/Linux) but it seems that I can't play any sound file on this OS. It is working perfectly on my windows machine, so I guess the problem is not into my code.

I'm using this dependencies :

"dependencies": {
    "@google-cloud/text-to-speech": "^0.4.0",
    "cors": "^2.8.5",
    "discord.js": "https://github.com/discordjs/discord.js.git",
    "express": "^4.16.4",
    "ffmpeg-binaries": "^4.0.0",
    "node-opus": "^0.3.1",
    "text-to-mp3": "^1.0.4"
  }

Every time I try to play a file voiceConnection.play('./aaa.mp3'); I get this error

(node:15624) UnhandledPromiseRejectionWarning: Error: Could not find an Opus module! Please install node-opus or opusscript.

I don't understand what this 'Please install node-opus or opusscript.' msg means since I do have node-opus as a dep.

Notice : I tried opusscript, but I got another error :

events.js:183
      throw er; // Unhandled 'error' event
      ^

ffmpeg is installed on my vps :

I just made a change to Discord.js very recently, can you try reinstalling all your modules - especially prism-media - and tell me if this fixes your issue?

[GuillaumeNachury]

I just did a rm -Rf node_modules and gave yarn a run. I still got the error, should a I use a specific branch ?

[amishshah]

Could you try providing an absolute path to the audio file and see if that works?

[GuillaumeNachury]

Yes I already tried that using hardcoded value or via path.join(process.cwd(),"aaaa.mp3");

[amishshah]

That's strange, maybe it's because your FFmpeg is pretty out of date? Could you try uninstalling ffmpeg-binaries, see if that fixes the problem. If it doesn't, try updating FFmpeg on your VPS. Tell me if that still doesn't work and I'll do some more investigation tomorrow.
