Additional description

It worked fine a few days ago, but suddenly I got this error. I've tested this on other systems and also encountered the same symptom. So I wonder if the ionic template has some changes?

Looks like you are using the old ionic CLI, it was renamed to @ionic/cli long ago.

npm uninstall -g ionic
npm install -g @ionic/cli

You already reported it on ionic-cli repository and already told you this

ionic-team/ionic-cli#4702
