The regenerator/runtime module is deprecated; please import regenerator-runtime/runtime instead.

1.判断是否已经安装了babel的拓展包(Polyfill)

  如果没有安装，就去安装  npm install --save-dev babel-polyfill 安装polyfill

 一般情况下，package.json文件中,已有，

"devDependencies": {
    "babel-polyfill": "^6.23.0"
  }

2.在姓名JS文件开头添加 import "babel-polyfill";
