node.js - NPM node-sass installation fails

Question

I am trying to install node-sass in a project, which perfectly builds and runs on my pc but on my surface I am having major issues when trying to install the packages.

Note: I have tryed reinstalling and rebuilding the project several times.

Summary of the error:

You're using Node 12, and node-sass needs to be at least 4.12 to support that version https://github.com/sass/node-sass#node-version-support-policy
