van-cascader按需引入报错

报错：<van-cascader> - did you register the component correctly? For recursive components, make sure to provide the "name" option

解决：利用全局引入，或者使用组件的 name 属性作为键来解决

1.全局引入

//在当前页或者main.js直接全局引入
import { Cascader } from "vant";
import Vue from "vue";
Vue.use(Cascader);

2.利用Cascader.name: Cascader来局部引入

//在当前页按需引入即可
import { Cascader } from "vant";
components: { [Cascader.name]: Cascader },
