Problems upgrading angular 5 project to angular 6, and upgrading angular on a PC

I had serious issues trying to upgrade an existing project, and it was not clear online what I should do.

The main persistent error was:-

./node_modules/raw-loader!./node_modules/postcss-loader/lib??embedded!./node_modules/sass-loader/lib/loader.js??ref–8-3!./src/styles.scss
Module build failed: Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (64)
For more information on which environments are supported please see:
https://github.com/sass/node-sass/releases/tag/v4.8.3

The online information on this was not clear.

Initially I used a liberal combination of npm-update and npm-update –g on various things but still had the above error.

I reached a point of installing primeng successfully under angular 6 as detailed here.

I then tried hand editing the package.json file for the upgrade project, stealing the versions from the package.json for the primeng application. However this did not appear to help -I still had the above issues.

In the end a combination of the following resolved this:-

ng update @angular/cli

ng update @angular/cli

npm install –g node-sass@latest

npm install node-sass@latest

I think the key issue here was installing the latest node-sass. I also had some code errors to resolve in the application but I did mange to run it successfully.
