Webpack babel 转译到 es5 不太好用

Question

I'm trying to build my ES7 source code into a single file and have it transpiled down to ES5 but when I run webpack I still notice code like this in the built bundle

t.exports=class extends n(0).Component{title(){return this.constructor.name}}}

The export of the class means that something is not quite working, this is my relevant webpack config

module: {
    loaders: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ["env"]
          }
        }
      },

What am I doing wrong?

为了节省其他人我浪费的宝贵的几个小时 - 我包含了包含来自 node_modules 的 ES5+ 代码的库，而且很明显，配置忽略了 node_modues，所以我只需要删除该行。
