cant install- loads of node errors

[mcplums]

I get a crazy list of node errors when I try and install this. I'm using:

npm 6.11.3 node v11.13.0

I have a friend who has the exact same versions and he isn't getting any errors (we're also using the same package.json), so it isn't caused by the wrong version. Here is a sample of the errors, I will not copy it all:

Andrews-MBP:RealityCardsFrontEnd mcplums$ npm install

> node-gyp rebuild

Wat do?
