  //babel重要的loader在这里
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        loader: 'babel',
        include: APP_PATH,
        query: {
          //添加两个presents 使用这两种presets处理js或者jsx文件
          presets: ['es2015', 'react']
        }
      },
      {
        test: /\.scss$/,
        loaders: ['style', 'css', 'sass']
      }
    ]
  },
  // webpack所要搜索的文件
   resolve: {
      extensions: ['', '.js', '.jsx',]
  },
  plugins: [
    new HtmlwebpackPlugin({
      title: 'My first react app'
    })
  ]
}

提示的错误信息：但是index.jsx确实是在项目根目录里面的

看你的问题，你并没有app这个文件夹吧，但是入口文件却设置为是app下的index.jsx，entry那里的APP_PATH 用 ROOT_PATH 应该就可以了
