Updated npm by mistake and ionic broke ionic 2

I updated npm by mistake and after that I’m getting errors for missing files , so I thought if I update node that would help but apparently it doesn’t XD
so here is one of the errors that appears :
Module build failed: Error: ENOENT: no such file or directory, open '/Users/mr3bood/Desktop/dev/myApp/node_modules/@angular/core/@angular/core.es5.js'

What exactly and how did you update?
In general Ionic doesn’t really care to much about node and npm versions and is fine with any recent or LTS release. Please post your ionic info output and npm+node versions so we know what are are dealing with.

ionic info :
Your system information:

Cordova CLI: 6.4.0
Ionic CLI Version: 2.1.18
Ionic App Lib Version: 2.1.9
ios-deploy version: 1.9.0
ios-sim version: 5.0.13
OS: macOS Sierra
Node Version: v7.9.0
Xcode version: Xcode 8.3 Build version 8E162

npm : 4.5.0
node : 7.9.0

You should probably update your Ionic CLI - it’s quite old. 2.2.3 is the current stable version.

I would try to delete the node_modules folder and then execute npm install in the project directory again.

I’ve deleted the node_module folder and run the command :
npm install
but when I run the command :
ionic serve
I get this errors :

npm ERR! errno 1
