安裝 babel-polyfill ``` npm install -save-dev babel-polyfill ``` 配置 ``` webpack.base.conf.js文件的 module.exports 的 entry 改為 app: ['babel-polyfill', './src/main.js'] module 下 添加 resolve('static') 把static文件夾下的js也進行轉義 { test: /\.js$/, loader: 'babel-loader', include: [resolve('src'), resolve('test'), resolve('static')] }, ```
