這是報的錯誤

var path =require('path');
module.exports = {

//入口文件
entry:'./app/index.js',
//出口文件
output:{
    filename:'index.js',
    path:path.resolve(__dirname,'dist'),
    publicPath:'temp/'   
},
devServer:{
    contentBase:'./',
    host:'localhost',
    compress:true,
    port:1717
},

// module:{
// loaders:[
// {
// test:/.js$/,
// exclude:/node_modules/,
// loaders:"babel-loader",
// query:{
// presets:['es2015','react']
// }
// }
// ]
// }
module: {

rules: [
  {
    test: [/\.bmp$/, /\.gif$/, /\.jpe?g$/, /\.png$/],
    loader: require.resolve('url-loader'),
    options: {
      limit: 10000,
      name: 'static/media/[name].[hash:8].[ext]',
    },
  },
]

}

這是webpack.config.js 文件，這個文件應(yīng)該配置有錯誤，那個大神，還是錯誤呢
