Node.js install ws error with python

Question

Got python version 3.5.0 installed (Thanks to Hiren S.) for saying I didn't have it installed. Now I am getting this error when I try to install ws (web socket.) Still have no idea what error I am getting or what it means.

Answer 1

Python version 2.7 works with Node js (not version 3.x.x). Try to install instead this version : 2.7.11. Then check your path of Python : C:\Python27\ and C:\Python27\Scripts

Then in your command as administrator, run npm install --global --production windows-build-tools

Answer 2

You did not installed Python or PYTHON environment variable is not set.

you have to download python from here : https://www.python.org/downloads/

• Grimmrp Support: Alright I installed Python and now I am getting a different error. Will update my post now.
