Cannot read property 'indexOf' of undefined

I'm using WIndows x64, and Node 4.4.7.

When I using CLI, is returning fallowing error for me.

$ wifi-password
TypeError: Cannot read property 'indexOf' of undefined
at C:\Users\myUser\AppData\Roaming\npm\node_modules\wifi-password\cli.js18:18
at process.tickCallback (node.js369.9)

That one is weird. Basically it means you're getting an error but err.message is undefined.
