You're using composer 2. Vanilla for some reason won't upgrade from Composer 1.

Solution: use composer v1

Composer 1 is being retired, just got off the phone with chad.

You can use both versions of the composer if you set up your server to do so but most folks are not going to do that. It's sad because I really dig the vanilla forum.
