v-dialog覆盖不显示：/

Question

我在项目中使用带有vuetify框架的vuejs，并且所有组件都能很好地工作，但是 v-dialog（https://vuetifyjs.com/en/components/dialogs#api）不显示覆盖，但其他属性起作用：/

我没有使用Hide-overlay属性

app.js

   require('./bootstrap');

    import 'vuetify/dist/vuetify.min.css'

    import Vue from 'vue'
    import VueRouter from 'vue-router'
    import Store from './store'
    import vuetify from 'vuetify'

    import Desk from "../js/components/pages/Desk"; 


    Vue.use(Store)
    Vue.use(vuetify, {
        theme: {
            primary: '#f24055',
            secondary: '#3f4167',
            accent: '#ffffff',
            error: '#ffffff'
        },
        rtl: true
    })
    Vue.use(VueRouter) 
    Vue.use(Desk) 

    const routes = [
        {path: '/desk', component: Desk}, 
    ]

    const router = new VueRouter({
        mode: 'history',
        hash: false,
        routes
    })

    new Vue({
        router, 
        Store
    }).$mount('#app')

很多Tnx
