引入流程：

1、编辑app.json，添加：

"useExtendedLib": {
  "weui": true
}

2、编辑页面的json文件，如下：

{
  "usingComponents": {
    "mp-dialog": "weui-miniprogram/dialog/dialog"
  }
}

3、编辑页面wxml文件，如下：

<mp-dialog title="test" show="{{true}}" bindbuttontap="tapDialogButton" buttons="{{[{text: '取消'}, {text: '确认'}]}}">
    <view>test content</view>
</mp-dialog>

4、编译报错，异常栈如下：

是我操作不对还是文档缺失？或者与工具版本有关？我是稳定最新版，版本号为1.03.2011120，已看到有其他人遇到相同问题没有人回复。
