未定义'regeneratorRuntime'

Question

我正在使用Vue.js，我需要从特定文件下载JSON数据。我下载了一个软件包“ vue-json-to-excel”，也将其导入到main.js ofc中。控制台警告多个错误“工作站未定义”，“预期功能”和“无法获取未定义或空引用的属性'length'” 我从未使用过此JavaScript包，因此我只使用了其站点中的代码，对我而言不起作用。

Main.js：

import JsonExcel from 'vue-json-to-excel'
Vue.component('downloadExcel', JsonExcel)

这是组件的文件，我希望该下载按钮位于其中：

    <template>
          .
          .
          <div class="col-6">
              <canvas id="temperaturechart" width="750" height="400"></canvas>
              <downloadExcel
                class = "btn btn-default"
                :data = "stations"
                :fields = "temperatures"
                name = "filename.xls">
                Download
              </downloadExcel>
          .
          .          
    </template>

    <script>
    import temperatureChartData from '../temperature_chart.js'
    import { stations } from '../json/data.json'
export default {
  components:{
    .
    .
  },
  .
  .
  computed: {
    temperatures() {
      return stations(
        ({
          temperatures,

      }) => ({
          temperatures,

      }))
    }
  },

这是我要从中下载这些数据的JSON文件：

有人可以帮我吗？
