I tried to make an ASP.NET Core app with a react frontend, so I run the command:

dotnet new react -o <project name>

This created a project that was runnable. The problem was that it couldn't run sass files.

So I tried to install the node-sass with the "npm install node-sass" on the client folder containing the node-modules folder.

It install find. but gave me a "Node Sass version 6.0.1 is incompatible with ^4.0.0"

I been googling this. and so far everyone been saying you need to uninstall the new version and install it running version "node-sass@4.14.1" like mentioned here

But it failed to install.

I think the easiest thing for you to do is remove node-sass with npm uninstall node-sass

and then install sass which you can find the npm for here with npm i sass --save

I've used the sass library over the node-sass library since I had a similar problem. It has all the same stuff and works the same with React
