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.

C:\Documents and Settings\Grimm>npm install python
python@0.0.4 node_modules\python

C:\Documents and Settings\Grimm>npm install ws

Answer 1

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

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

Answer 2

Python version 2.7 works with Node js (not version 3.xx). 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
