调试基础库是3.2.4，配置代码如下：

<picker-view indicator-class="picker-indicator" value="{{date}}" bindchange="bindPickChange">
    <picker-view-column>
      <view wx:for="{{years}}" wx:key="{{years}}" class="picker-item">{{item}}年</view>
    </picker-view-column>
    <picker-view-column>
      <view wx:for="{{months}}" wx:key="{{months}}" class="picker-item">{{item}}月</view>
    </picker-view-column>
    <picker-view-column>
      <view wx:for="{{days}}" wx:key="{{days}}" class="picker-item">{{item}}日</view>
    </picker-view-column>
  </picker-view>

在微信开发工具中报，并且indicator-style和indicator-class不生效
