Почему не работает vuelidate?

Установил vuelidate: npm install vuelidate main.js:

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import './index.css'
import './assets/tailwind.css'
import Vuelidate from "vuelidate";

createApp(App).use(store).use(router).use(Vuelidate).mount('#app')

Пытаюсь в компоненте вывести переменную $v, но ничего не происходит. В консоли предупреждение:

[Vue warn]: Property "$v" was accessed during render but is not defined on instance.
