webpack打包压缩 ES6 js react报错：
升级到 babel6 了
ERROR in /Scripts/Test/test.bundle.js from UglifyJs
Unexpected token punc ?(?, expected punc ?:? [/Scripts/Test/test.bundle.js:22901,
解决方案：
安装 babel-preset-es2015
npm install babel-preset-es2015 --save
配置babel
//加载器配置
loaders: [
{
test: /\.jsx$/,
loader: ‘babel-loader‘,
query: {
presets: [‘react‘, ‘es2015‘]
}
}
