The method to solve issues on npm install web3 on Windows 10

Hi everyone,

I've gone through a couple tough ways setting web3 up on my machine and run it. After digging through the internet, I found many people has this issues, but most of the solutions are not working for me.
After I tried on several different methods, I found this way works on my machine (Windows 10 Pro). Now, I'm able to install web3 with no issue. (Or other packages related to node-gyp issues, such as "truffle unbox react")

I thought it would be great if I can post it here and wish to help people save their time if they are trying to set up web3 like me :P

So, first the error I received is some processes from "node-gyp rebuild" error and "scrypt" related issues. If you received some errors other than this, then this method might not be helpful to you.

Steps I took to solve this issues:

1. Install NodeJS, Git

2. Download Windows Visual Studio 2015
   a. Open Visual Studio 2015 and create "new project..."
   b. Select "Create new C++ project"
   c. You should see a menu that VS requested to install "Common Tools for Visual C++ 2015" and "Windows 8.1 SDK and Universal CRT SDK" (some processes in scrypt required tools from this Windows 8.1 SDK files)
   d. Select both and install

3. Install/link python through npm command
   npm --add-python-to-path="true" --debug install --global windows-build-tools

4. Set msvs_version to 2015
   npm config set msvs_version 2015 --global

5. Install web3
   npm install web3

For the reference:
My npm version : 5.6.0
My node version: 8.9.4

Hope this would help!
