Solution to issues with node-gyp & node-sass on Windows

I was trying to setup a new project using the Angular CLI and of course when I got to the point to do yarn install or npm install I got some issues. The issues had to do with node-sass and me not having node-gyp and Python on my machine.

Step 1 - Python via Visual Studio

As I am a happy .NET developer (thanks Microsoft for awesome IDE's & tooling support) I have Visual Studio 2017 and 2019 installed and just added the Python stuff in there. I installed both Python v2.7 and v3.

I have NOT installed the windows-build-tools package as many suggests.

Step 2 - Environment variable

I pointed the PYTHON envorinment variable to v2.7


Step 3 - node-gyp & npm config

npm install -g node-gyp
npm config set python "C:\Python27amd64\python.exe"
npm config set msvs_version 2017


I was now able to do:

npm install -g @angular/cli
ng new mat-lab
    --prefix matlab
    --routing true
    --style scss
    --skip-install true
    --skip-git true
npm install

Resulting in no more build errors or what so ever. No node-gyp or node-sass issues.

Hope it helps.
