Unable to npm install web3 on Windows 10 - node.js

Question

I followed every thing on this page:
https://medium.com/#PrateeshNanada/steps-to-install-testrpc-in-windows-10-96989a6cd594
Except step number 5 where my Node.js version is 8.10.0 instead of 8.10.2 which iI dont think is a big difference.
I have installed VS 2017 Community Edition, Windows 10 SDK, OpenSSL, npm-gyp.
I have run the command npm install --global --production windows-build-tools to install all the latest build tools and still get this error. Help is needed.

It appears to me that node-gyp rebuild is failing on my machine. Why is that?

Answer 1

Did you try running the command
npm install --global --production windows-build-tools
in powershell?
I had the same issue and running the command in powershell worked.
