Replacing node-sass with sass, resolved this issue for me.

Also remove package-lock.json before npm install to regenerate it.

What version of Node are you using? No luck for me after adding "sass": "^1.77.4"

Another issues states node 8.17.0 - but that cannot be right because...

sharp: Installation error: Expected Node.js version >=10 but found 8.17.0
sharp: Please see https://sharp.pixelplumbing.com/install for required dependencies
