I copied code from
Vuetify Data Iterator Filter part
I can use other Vuetify components like
v-btn
,
v-card
,
v-data-table
,
v-data-iterator
, etc.
Only
<v-list-item>
and
<v-list-item-title>
throw errors.
I have no idea what is going on.
Error messages:
[Vue warn]: Unknown custom element:
<v-list-item>
- did you register
the component correctly? For recursive components, make sure to
provide the "name" option

As you can see, other components are working well...
I read the Vuetify Quick Start again and make sure I install Vuetify correctly.
Below is src\plugins\vuetify.js file
import Vue from 'vue'
import Vuetify from 'vuetify/lib'
import 'vuetify/src/stylus/app.styl'
Vue.use(Vuetify, {
iconfont: 'md',
and src\main.js
import Vue from "vue";
import firebase from './components/firebaseInit';
import App from "./App.vue";
import router from "./router";
import vuetify from './plugins/vuetify' // path to vuetify export
Vue.config.productionTip = false;
let app = '';
// initialize the Vue app only when we are sure Firebase is initialized
firebase.auth().onAuthStateChanged(() => {
if (!app) {
app = new Vue({
vuetify,
router,
render: h => h(App)
}).$mount("#app");
I tried to import the components manually but still, the same errors occurred:
import { VListItem, VListItemTitle } from "vuetify/lib";
export default {
components: {
'v-list-item': VListItem,
'v-list-item-title': VListItemTitle
