vue 項目 在ie瀏覽器下頁面顯示為空

npm install --save babel-polyfill

在main.js中添加：

import es6Promise from "babel-polyfill";
es6Promise .polyfill();

在webpack.base.conf.js中修改

module.exports = {
  entry: ["babel-polyfill", "./app/js"]
};

但是還是發現報錯：

polyfill-eventsource added missing EventSource to window

這時候再下載event-source-polyfill模塊

npm install event-source-polyfill --save-dev

並將webpack.base.conf.js修改為：

module.exports = {
  entry: ["event-source-polyfill", "babel-polyfill", "./app/js"]
};
