vue.js - How to fix this node-sass build error on Netlify?

Question

I've done this many times in the past, I'm getting this error in the netlify logs. The repo I am attempting to deploy is https://github.com/yanyamz/Key_Visual_Arts.

I checked to see if it was within size limitations of Netlify and it is, totally 15mb or so vs the 20+mb that you can deploy on netlify.

Answer 1

Stop using node-sass

1. it is native node package, which means it requires some build tools to be installed in some environments (prebuild binaries for some OS/environments are distributed in NPM package but obviously not for one used by netlify)

2. On top of that it is already deprecated

Just uninstall node-sass and install sass - sass-loader should switch to it automatically
