Strange npm error when running npm install brain.js

Question

When trying to install brain.js, a strange error occurs and I can't understand what the problem is and where does the python come in since this is the installation of a library through npm. I didn't find similar situations in Google (I don’t even understand how to google this).

G:\firststep\BR>npm i brain.js

> gl@4.3.3 install G:\firststep\BR\node_modules\gl
> prebuild-install || node-gyp rebuild

prebuild-install WARN install No prebuilt binaries found (target=10.14.2 runtime=node arch=x64 libc= platform=win32)

There is not a word about this problem in the documentation for brain.js. Everything is simple there - run npm install brain.js and that's it.

UPDATE 16.08.2019

This instruction marked option 2 helped me https://github.com/nodejs/node-gyp#on-windows

Answer 1

Use the command without dot:

npm install brainjs

Answer 2

Make sure the Path and Env variables are set for the Python installed. Also, I found something similar here.. hope it helps!!
