vue-cli新建vue项目安装axios后在IE下报错

使用脚手架新建了一个vue项目，可以在IE9+浏览器运行，但是在添加了axios后，在IE下就报错了

首先是安装axios，在命令行执行：

$ npm install axios -s    //执行命令，下面是输出结果
+ 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的页面引入：

import axios from "axios";

然后添加使用的代码：

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

报错图片：

接着又在methods的前面添加了：

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

然后又报错了：

解决方法; 安装 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

安装成功后，在main.js 引入

引入后再次运行项目,也就是执行 npm run dev ，然后在IE下查看是否请求数据成功，这里是请求数据成功了的，如下图：
