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)
