vue2.0 webpack 打包后chrome 控制臺顯示 Cannot read property 'call'

vue2.0 webpack^1.13.2 打包文件后chrome 控制臺顯示 Cannot read property 'call' of undefined at webpack_require (vue.js:588)

后來發(fā)現(xiàn)是引入了這個組件就打包不成功，不過熱更新修改文件后又都可以正常顯示

<template>
  <div class="banner" :style="{ backgroundImage:'url('+ BannerData[0].imgUrl +')'}"></div>
</template>

<script>
import Vue from 'vue'
