vue做的项目IE下显示空白 调试报错 求解

Question

polyfill-eventsource added missing EventSource to window
promise is undefiend

Answer 1

App.vue里加import 'babel-polyfill'

"devDependencies":{
"babel-polyfill": "^6.22.0",
...
}

Answer 2

执行：

npm install --save babel-polyfill

Because this is a polyfill (which will run before your source code), we need it to be a dependency, not a devDependency

不能放在devDependency里面，而且之前需要在入口文件中引入

import 'babel-polyfill'

参考：https://babeljs.io/docs/usage...

Answer 3

vue是IE9起跳啊，而且你这里也需要补个promise的Polyfill

Answer 4

最后问题怎么解决的？

Answer 5

把element-ui的路径加到babel路径中
