Vue + Vant 图片懒加载 提示:Failed to resolve directive: lazy

vue + vant 使用图片懒加载 提示:Failed to resolve directive: lazy

报错代码:

  <img v-lazy="item.GoodImg" alt="">

问题解决:main.js 引用Lazyload 懒加载框架

import Vant from 'vant';
import { Lazyload } from 'vant';
import 'vant/lib/index.css';

Vue.config.productionTip = false
Vue.use(Vant)
Vue.use(Lazyload)
