this my environment:-

Ionic Framework: 3.7.1

Ionic App Scripts: 3.0.1

Angular Core: 4.4.3

Angular Compiler CLI: 4.4.3

Node: 6.11.4

I tried to solve this problem by uninstalling npm, ionic, all cordova plugins and reinstall them.

the big problem is I cannot understand where is the error and what is the part which makes this error !!??
