NPM install errors on node-sass - node.js

Question

I tried installing SASS, I tried reinstalling Node, I tried NPM install globally.
I made this project a few months ago. I cloned it from GitHub and it seems to be okay as far as that goes.
I also keep getting this error when trying to npm start the application:
'react-scripts' is not recognized as an internal or external command, operable program or batch file.

Answer 1

You can follow the pointers in the npm error log. It tells you that python is not found on your system. Try to install python2 (see the EOL release https://www.python.org/downloads/release/python-2718/), then see what npm tells you.
