Displaying VUE CDN

I can’t display v-for using CDN

const Gallery = { template: '{{$t('gallery')}} <img :class="[[item.class]]" v-for="(item, index) in carousel" :src="[[item.img]]" alt="img" />' }

const routes = [
    { path: '/', component: Gallery }
];

// CDN app.use(i18n);
// CDN app.use(router)
// CDN app.mount("#app");

I can’t show the following v-for using Vue View CDN
