Cordova install throws an error, what's wrong?

Question

Node.js

I installed node.js for windows, installed Git, installed cordova: npm install-g cordova, gives me:

c:\>npm install -g cordova
npm WARN deprecated [email protected]: request has been deprecated, see https: //git
hub.com/request/request/issues/3142
npm WARN deprecated [email protected]: this library is no longer supported
C:\Users\Aser\AppData\Roaming\npm\cordova -> C:\ Users\Aser\AppData\Roaming\npm\n
ode_modules\cordova\bin\cordova
+ [email protected]
updated 1 package in 123.242s cordova

commands don't work i.e. not installed. What am I doing wrong?
