I am installing a certain NodeJS script - Caress. But i am not unable to. I am using Windows 8.1, can anyone tell me what is the problem i am facing, and why is this installation not working. There seems to be a problem with the buffertools dependency, thats far as i can think. Dont know how maybe fix this?

If i download the build from github and place it in node-modules, nothing seems to work. when i try to start, using npm start, or during implementation either.

G:\nodejs\node_modules\caress-server>npm install

G:\nodejs\node_modules\caress-server>npm start

> caress-server@0.1.1 start G:\nodejs\node_modules\caress-server
> node examples/server.js

info - socket.io started

As commented below you may not need to install VS on windows, check this out

UPDATED 02/2016

Some npm plugins need node-gyp to be installed.

However, node-gyp has it's own dependencies (from the github page):
