为什么Babel在我的vue.js组件中抛出错误？

Question

<template>
  <div emptyDiv>
    <h3> Stages </h3>
    <table :style="tableStyle">
      <tbody>
        <template v-for="item in jobs">
          <tr>
            <td v-for="stage in item.stage_exec" :style="getStyle(stage.build_id)" :title="stage.build_id" >
              [[ stage.cleanDuration ]]
            </td>
          </tr>
        </template>
      </tbody>
    </table>
  </div>
</template>

<script>
import Vue from 'vue';
import moment from 'moment';

export default {
  delimiters: [ '[[', ']]' ],
  props: ['jobs'],
  computed: {
    tableStyle() {
      return {
        'background-color': '#f9f9f9',
        'border-color': '#C0C0C0',
        'padding': '8px',
        'width': '100%',
        'display': 'table',
        'table-layout': 'fixed',
      };
    },
    emptyDiv() {
      return {
        'display': 'contents',
      };
    },
  },

    getStyle (name) {

      milliseconds = parseInt((duration%1000)/100)
      seconds = parseInt((duration/1000)%60)
      minutes = parseInt((duration/(1000*60))%60)
      if (minutes < 10) {
        minutes = '0' + minutes
      }
      if (seconds < 10){
        seconds = '0' + seconds
      }
      return minutes + " m " + seconds + " s " + milliseconds + ' ms'
      }
  },
  created() {
    testEndpoint = 'http://testurl'
    fetch(testEndpoint)
    .then(body => {
      cleanStartTime = moment(body[0].time_start)
      cleanEndTime = moment(body[0].time_end)
      cleanDuration = this.calculateDuration(cleanStartTime, cleanEndTime)
      this.job_execs.push({
        'name': body[0].job.name,
        'build_id': body[0].build_id,
        'env': body[0].job.env,
        'time_start': cleanStartTime.format('LLL'),
        'time_end': cleanEndTime.format
      })
    })
    .catch( err => {
      this.isEmpty = (this.binaries.length == 0) ? true : false;
      console.log('Error Fetching:', testEndpoint, err);
      return { 'failure': testEndpoint, 'reason': err };
    },
},
</script>

当我尝试维修组件时，它无法编译，并且不断出现无法识别的babel错误。

Unexpected token (117:2)

Unexpected token (117:2)

  115 |       return { 'failure': testEndpoint, 'reason': err };

  119 | 

那什么是意外令牌？
