Answer 3

You should try to install SASS.

I remember havign this issue in AngularJS with compass, I had to install it with Ruby to make it work. This was 3 years ago, so I'm not sure this would be the solution, but it doesn't cost anything except time to try, right ?

Node-sass@4.5.0 cannot be installed on node 8

Please update either node-sass or node version compatible

I had the same issue with a new install with Keystone.js. I was able to get pass this issue by removing Node Sass from package.json and running npm install again. Being that the package wasn't listed under node modules. And it worked fine after that.
