Ionic Framework update to stable version

Question

Trying to update previous Ionic Framework beta to v2. I have updated Cordova first, but the IonicFramework continues in beta instead of having run the update command.

This is the environment:

Cordova CLI: 6.5.0 
Ionic Framework Version: 2.0.0-beta.11
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: macOS Sierra
Node Version: v6.3.1
Xcode version: Xcode 8.2.1 Build version 8C1002

And these are the issues when I do sudo npm install -g ionic:

try uninstalling ionic globally and then installing again:

npm unistall -g ionic
npm install -g ionic
