I’m trying to create a project for an android app using Ionic framework, but I get this error while creating the project :

Unable to add plugins. Perhaps your version of Cordova is too old. Try updating (npm install -g cordova), removing this project folder, and trying again. (CLI v1.7.14)
there is the system confguration :

Cordova CLI: 6.0.0
Ionic Version: 1.2.4
Ionic CLI Version: 1.7.14
Ionic App Lib Version: 0.7.0
OS: Distributor ID: Ubuntu Description: Ubuntu 14.04.4 LTS 
Node Version: v0.10.25

I have read a tutorial about installaton and for my final test I have use ths script : https://blog.nraboy.com/2014/09/install-android-cordova-ionic-framework-ubuntu/

but I stll get this error
