wepy2.0中使用vant-weapp组件

npm i vant-weapp -S --production

在项目下的package.json下看是否有了vant字段

最最最重要的，在引入的时候通过module映入

<config>

{

    navigationBarTitleText: 'WePY 2.0 Feature Demo',

    usingComponents: {

    panel: '~@/components/panel',

    counter: '~counter',

    list: '../components/list',

    group: '../components/group',

    "slide-view": "module:miniprogram-slide-view",

    "van-button": "module:vant-weapp/dist/button/index"

    }

}

</config>

<van-button type="danger">危险按钮</van-button>
