问题：Vue项目开发环境中在IE11正常运行，打包之后发布上线在IE11中报Promise 未定义
1.重要：确保webpack是2.6.1的版本，如果不是在package.json将webpack修改为”webpack”: “2.6.1”
I had this issue even with adding babel-polyfill, because of a bug with webpack 2.6.0. Upgrading to 2.6.1 solved the issue.
(由于webpack 2.6.0存在错误，即使添加了babel-polyfill，我也遇到了这个问题。 升级到2.6.1解决了这个问题。)

修改package.json中webpack: ‘2.6.1’之后，如果npm run build打包报错，解决方法： 删除node-modules文件夹，重新npm install
2.webpack.base.conf.js 文件修改为
entry: {
app: ['babel-polyfill', './src/main.js']
},3.main.js 文件在第一行添加
import 'babel-polyfill'官网使用polyfill的文档：https://babeljs.io/docs/en/babel-polyfill/#usage-in-node-browserify-webpack
