Your Cordova tooling seems to be out of date, which might be causing all kinds of problems.
You can read about how to figure out the current Cordova versions and how to update CLI, platforms and plugins here: How to update Cordova CLI, Platforms and Plugins · ionic.zone

Your Ionic CLI is also really out of date. You should update with npm install -g ionic
