javascript - ar-drone module not found, where to place it? -


i trying hack ar drone 2.0, following tutorial: http://www.instructables.com/id/autonomous-ar-parrot-drone-20-flying/?allsteps

i have installed node on d: drive , installed ar-drone module on in node_modules folder. tried 

var ardrone = require('ar-drone');

command says "undefined". tried writing .js file , executing cmd, , responds

"error cannot find module 'ar-drone'"

i moved ar-drone folder different places(in node_modules folder in folder saved .js file) drone still standing on ground 4 of legs :(

i of course connected drones wifi, don't think problem lies there.

if can't find ar-drone, need execute line again , see there no errors:

npm install ar-drone
