Node-sass error during installation of node modules

Question

I'm trying to install Laravel on my Debian server, but it fails during installation of node-sass. I have had this setup for a long time and never experienced issues before. Maybe node-sass or npm changed something recently?

Hope you can help me, I have been stuck for 2 days now.
