npm & ionic shows different version in different folders

Question

I have weird issue with installing ionic and npm.

Until yesterday, I could build an app without any issue. I've tried to update ionic 2 version and it's updated to 2.1.18, but when I check

ionic -v

in cmd I get the same problem that when I installed ionic.

It shows me the version and it shows me this error I copied from the CMD. You can see different folders and how it makes the problem

C:\Users\adirz>npm -v 4.0.5

C:\Users\adirz>ionic -v 2.1.18

C:\Users\adirz>cd myapps

C:\Users\adirz\myapps>cd haversami

C:\Users\adirz\myapps\HaverSami>npm -v 3.10.9

C:\Users\adirz\myapps\HaverSami>ionic -v 'ionic' is not recognized as an internal or external command, operable program or batch file.

C:\Users\adirz\myapps\HaverSami>

Install npm locally in your project folder

npm install npm --save-dev
