Answer 1

This is something related to the latest version of NodeJS which is explained here . I would advise you below two options to get rid of this. Choose the best that suits you.

• Please setup python in your machine
• Downgrade your Nodejs to version 10.X and try it. I am using 10.18.0 and it works perfectly fine. You can download it from here .

Cheers!
