Hi! I'm trying to run the example on my Windows 10 PC and I get this error:

events.js:174

This happens when I run node example.js https://www.youtube.com/watch?v=MMuAqR_MjS8. I also have node 11.5.0 and npm 6.4.1.

The youtube stream requires ffmpeg and probably is not installed on your computer or is not in the PATH. You can force the library to use the right bin in this way https://github.com/chrvadala/create-music-stream#faq
