Vue.js不能在IE11上加载，错误'Symbol'不明确

在我的webapp上使用Vue.js在大多数浏览器上工作，IE11除外。我试过默认babel-preset-es2015，也试过babel-preset-es2015-ie，但没有运气：代码仍然没有运行在IE11上'Symbol'未定义错误。Vue.js不能在IE11上加载，错误'Symbol'不明确

.babelrc

{ 
    "presets": ["es2015"] << also tried es2015-ie 
}

的可能的复制[ '符号' 未定义在IE中使用后，巴贝尔（HTTP：// stackoverflow.com/questions/33828840/symbol-is-undefined-in-ie-after-using-babel） –

正如@Leonid指出，我错过了浏览器的填充工具脚本，由this answer描述。现在在IE11（和其他浏览器）上正常工作。

这里是我做过什么：

npm install --save-dev babel-polyfill

webpack.config.js

module.exports = { 
    entry: ['babel-polyfill', './src/main.js'], 
    .... 
    .... 
}
