vant-UI官网：【这个是vant3与vant-Webapp略有区别】

Vant 3 - Lightweight Mobile UI Components built on VueLightweight Mobile UI Components built on Vuehttps://vant-ui.github.io/vant/#/zh-CN

小程序端我们使用这个 ---> vant-Webapp

Vant Weapp - 轻量、可靠的小程序 UI 组件库

官网GitHub上下载这个包(dist)即可，或者下我挂这个网盘链接都可。

虽然并不知道到这个自定义组件为什么要用wxcomponents我试了其他名字（已找到原因，如下图：），但是不行，dist改为vant。

整个目录结构与pages同级：wxcomponents/vant/官方组件

 引入步骤：

1.首先在app.vue文件内添加：

@import "/wxcomponents/vant/dist/common/index.wxss";

 2.在pages.json文件内添加组件引用：

【用多少加多少，没必要全加，这里是常用的，便于复制】

圈起来这几个应该是必要的，可以试一下：

	},

3.测试使用：【跟着官网api使用即可】

	<!-- 测试vant -->
		<van-button type="warning">警告按钮</van-button>
		<van-button type="danger">危险按钮</van-button>
		
		<br>
		<van-switch v-model="checked" />

测试成功。
