使用 babel 后，IE 中未定义“符号" [英] 'Symbol' is undefined in IE after using babel

问题描述

我有一个使用 ES6 标准编写的 reactjs 应用程序，我使用 webpack 来构建它.webpack 使用 babel-loader 加载 js 模块.具体来说，我使用以下版本的软件包:<代码>├── babel@5.8.34├── babel-core@5.8.34├── babel-loader@5.4.0└── webpack@1.12.6

I have a reactjs app written using ES6 standards, and I use webpack to build it. The webpack loads the js modules using babel-loader. To be specific, I use the following versions of packages: ├── babel@5.8.34 ├── babel-core@5.8.34 ├── babel-loader@5.4.0 └── webpack@1.12.6

但是，在构建之后，IE 10 给出以下错误'Symbol' is undefined.babel 不应该定义 Symbol 吗?我需要设置 webpack 或 babel 的任何特定配置以使其工作吗?我在我的 .babelrc 中使用了 {stage: 0} 配置.

However, after building it, the IE 10 gives the following error 'Symbol' is undefined. Shouldn't the babel be supposed to define the Symbol? Is there any specific configuration for webpack or babel I need to set in order to make it work? I use {stage: 0} configuration in my .babelrc.

任何帮助将不胜感激，谢谢！

Any help would be appreciated, Thank you !

推荐答案

好吧，我最终发现 babel 单独没有 polyfill.包括脚本<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.6.15/browser-polyfill.min.js"></script>为我解决了这个问题.

Ok, I eventually found out that babel alone does no polyfill. Including script <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.6.15/browser-polyfill.min.js"></script> solved this issue for me.
