Always asked to upgrade even after I've done it


Despite the fact that I’ve installed the latest version of Ioninc and that I already did a successful “npm install -g cordova”, I always receive the following message on the command line :

Dependency warning - for the CLI to run correctly,
it is highly recommended to install/upgrade the following:

Please install your Cordova CLI to version >=4.2.0 npm install -g cordova

Is there any reason for that?
Even a npm update -g ionic didn’t help.

Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v6.9.4
Xcode version: Not installed


I am receiving the same warning… Tried uninstalling cordova and reinstalling but nothing removes this.
