ran
npm i -g @ionic/cli-utils@beta
with the result
@ionic/cli-utils@1.0.0-beta1
and
UNMET PEER DEPENDENCY strip-ansi@^3.0.1

... but with the same result (ionic serve -> TypeError: args.env.prompt)

You'll also need to update the cli globally with npm i -g ionic@beta (you should have beta10)

I'm not sure why it didn't also notify you of that update. I will investigate tomorrow.

This is the root of the problem. We should've used dots for the beta versions, apparently. Won't be a problem going forward.

Let me know if you still are having issues.
