npm WARN / extraneous (I have no idea what i'm doing)

[Tom O'Brien]

So I have managed to install nodebb somehow, by fumbling my way through tutorials but I have a few warnings in terminal.

Could someone please explain? and how to fix. Extremely grateful in advance!

Have you tried installing prefixer@0.0.3 using -g?
It would be something like this.
npm install -g prefixer@0.0.3
