Invalid command (CLI v1.7.10)

I was prompted to update, so I did and now I can’t run on Android.
This is a project I’ve recently started on so not too familiar with Ionic yet.

Your system information:

Cordova CLI: 5.4.1
Gulp version: CLI version 3.9.0
Gulp local: Local version 3.9.0
Ionic Version: 1.1.1
Ionic CLI Version: 1.7.10
Ionic App Lib Version: 0.6.5
Node Version: v4.2.1

How do I downgrade to the previous version?
