【报Bug】map组件导致热加载报错白屏

如题
index.vue内容

<template>   
    <view class=''>  
        <map ></map>  
    </view>    
</template>   
<script>  
    export default {   
        name: ''   
    }  
</script>    
<style lang='scss'>   
</style>

运行app，保存一次两次然后就会发现报错了，白屏

之前是没有这个问题的，更新之后2.0.4.20190706-alpha和2.0.2都有这个问题
