vue-cli新建vue項目安裝axios后在IE下報錯

使用腳手架新建了一個vue項目，可以在IE9+瀏覽器運行，但是在添加了axios后，在IE下就報錯了

首先是安裝axios，在命令行執行：

$ npm install axios -s    //執行命令，下面是輸出結果
+ axios@0.18.0
added 1 package from 1 contributor and audited 32846 packages in 12.611s
found 7 vulnerabilities (1 low, 1 moderate, 4 high, 1 critical)
  run `npm audit fix` to fix them, or `npm audit` for details

在用到axios的頁面引入：

import axios from "axios";

然后添加使用的代碼：

 methods: {
      getDatas (){
          this.msg = "觸發了"
          axios.get('http://192.168.80.129:8080/v1/topic/')
          .then(function(response) {
            console.log(response);
          });
      }
  }

接着又在methods的前面添加了：

mounted() {
    this.getDatas ();
},

然后又報錯了：

解決方法; 安裝 babel-polyfill

$ npm install babel-polyfill --save
npm WARN rollback Rolling back node-pre-gyp@0.10.0 failed (this is probably harmless): EPERM: operation not permitted, lstat 'F:\05 poverty alleviation project\poverty\node_modules\fsevents\node_modules'

+ babel-polyfill@6.26.0

  run `npm audit fix` to fix them, or `npm audit` for details

安裝成功后，在main.js 引入

引入后再次運行項目,也就是執行 npm run dev ，然后在IE下查看是否請求數據成功，這里是請求數據成功了的，如下圖：
