Uncaught SyntaxError: Unexpected token export

See original GitHub issue

引入echarts 导致,访问前段项目报错，如下图。

Version & Environment [版本及环境]

ECharts version [ECharts 版本]: 3.8.1 然后更新回3.7.2 还是同样的问题
Browser version [浏览器类型和版本]: chrome 61.0.3163.100
OS Version [操作系统类型和版本]: windows 10 和 macOS 都报同样的错误

Expected behaviour [期望结果]

ECharts option [ECharts配置项]

<script type="text/javascript">
  import echarts from 'echarts/lib/echarts'
  import 'echarts/lib/component/tooltip'
  import 'echarts/lib/chart/line'
  import 'echarts/lib/component/title'
  import 'echarts/lib/component/legend'
  export default{ 
    // vue 其他代码
   }
</script>

Other comments [其他信息]

因为我把引入highcharts 的代码给注释掉就可以正常访问了，除了这种方式，我还用了

let echarts= require('***')

的方式，会报同样的错误，我确定引入了 babel-preset-2015 也更新到了 babel-preset-env 但是还是同样的问题

The new version of echarts(v3.8.0) and its dependencies zrender(v3.7.0) change his module loading grammer from CommonJs(eg: require(‘xxx’)) to esModule(eg: import xxx from ‘xxx’). Some old module bundler like webpack(v1.0) can’t correct bundle esModule, so raise error. You can try below solution:

solution 1: lock the low version echarts and zrender low version echarts and zrender use the CommonJs to loader module. Old version module bundle can auto recognize it and bundle. Edit package-lock.json(will auto generate when npm >= v5.0), Change

"echarts": {
      "version": "3.8.0",
      "resolved": "http://registry.npm.taobao.org/echarts/download/echarts-3.2.3.tgz",
      "integrity": "sha1-TwHhW/2jNS/NjvkEnxPYRIlxolg=",
      "requires": {
        "zrender": "3.7.0"
      }
    },

"echarts": {
      "version": "3.2.3",
      "resolved": "http://registry.npm.taobao.org/echarts/download/echarts-3.2.3.tgz",
      "integrity": "sha1-TwHhW/2jNS/NjvkEnxPYRIlxolg=",
      "requires": {
        "zrender": "3.1.3"
      }
    },

And change

"zrender": {
      "version": "3.7.0",
      "resolved": "http://registry.npm.taobao.org/zrender/download/zrender-3.1.3.tgz",
      "integrity": "sha1-RFiX5ApDGkIk7w5xNXxh4tdJfIw="
    }

"zrender": {
      "version": "3.1.3",
      "resolved": "http://registry.npm.taobao.org/zrender/download/zrender-3.1.3.tgz",
      "integrity": "sha1-RFiX5ApDGkIk7w5xNXxh4tdJfIw="
    }

than rm -rf node_modules && npm install

solution 2: Enforce install the low version echarts and zrender directly:npm install echarts@3.2.3 && npm install zrender@3.1.3 Just a temporary solution.

solution3: update your module bundler(eg: use webpack2.0 or webpack3.0 instead webpack1.0)
