taro 3.0.17 Vue3 添加Vant-weapp，组件警告问题

jd_790505de4d7c7

引入vant-weapp
组件可以正常显示，但是会有警告信息：

[Vue warn]: Failed to resolve component: van-button 
  at <Index tid="pages/index/index" > 
  at <App>

请问这个怎么解决，应用上该配置的都配置了

代码如下：

  // index.config.js
  usingComponents: {
    "van-button": "../../components/vant-weapp/button/index"
  }

   // config/index.js
   patterns: [
      { from: 'src/components/vant-weapp/wxs', to: 'dist/components/vant-weapp/wxs' },
      { from: 'src/components/vant-weapp/common/style', to: 'dist/components/vant-weapp/common/style' },
      { from: 'src/components/vant-weapp/common/index.wxss', to: 'dist/components/vant-weapp/common/index.wxss' }
    ],

我这里@click事件也不能用，你那里可以吗
