Panel Area Plugin: Vue is not defined?

I’m currently building a panel area plugin, which uses tailwind ui and some more components, which i imported into my Vue view:

import { Disclosure, DisclosureButton, DisclosurePanel, Menu, MenuButton, MenuItem, MenuItems } from '@headlessui/vue'

There is no error when compiling. But when loading the page, an error occurs on the javascript console:

Uncaught ReferenceError: Vue is not defined

Why is Vue not defined, and what can i do?
