node-sass failure on npm install

[WesleyWaffles]

Fresh clone of the repo on my machine produces a failure on npm install. The error message is one I would expect if the node-sass repo was blocked by a proxy (I've encountered this at work), but I'm on a personal machine and network for this so I'm confused as to why it's happening. It appears to be this issue and just the version of some package or another is pointing to an unavailable node-sass version. Regardless, the details and error are below. I do not have this problem when creating new Angular app, so I wonder if version bumping this repo would solve it, but that can be challenging for sure. I'm going to try to continue the course using a WSL 2 Ubuntu instance and see how that goes.

Windows Version: 10.0.19041 Build 19041
Node Version: 12.18.2
NPM Version: 6.14.5
Angular CLI Vesion: 10.0.1

Can confirm this failed in my Ubuntu environment the exact same way. :/

Hi
The project is not updated with the latest version of the packages.
I fixed it with the following steps:

1. Update the packages to the latest:
   1.1 npm install -g npm-check-updates
   1.2 ncu -u
   2 Delete the local node_modules folder
   3 Install the npm
   3.1 npm install
   4 update the files polyfills.ts and test.ts with files from a new project.
   4.1 To create a new project run:ng new myNewProject
