Webpack Error React＆ES6以前はBabelifyで働いていました

Question

私はbabelify、watchify、browserifyからwebpack、webpack server、babelに移動しようとしました。

aws-sdkを使用しようとしたときに似たような問題が発生したため、6か月前にwebpackから離れることを覚えています。

何らかの理由で、私はビルドするたびに、私は次のエラーを取得する：

Hash: 396f0bfb9d565b6f60f0 Version: webpack 1.14.0 Time: 61ms [0] ./src/index.js 0 bytes [built] [failed]

私は必要に応じて、私はすべてが設定していると信じています。私のファイルを参照してください ：

webpack.config.js

module.exports = { 
entry: './src/index.js', 
    output: { 
    path: __dirname + '/public/js', 
    filename: 'bundle.js', 
    resolve: { 
     extensions: ['', '.js', '.jsx'] 
    }, 
    module: { 
    loaders: [ 
     { 
     test: /\.jsx?$/, 
     loader: 'babel-loader', 
     exclude: /node_modules/, 
     query: { 
      cacheDirectory: true, 
      presets: ['react', 'es2015'] 
     } 
     } 
    ] 
    } 
    } 
}

あなたはWebPACKのに誤りがありますconfig。 resolve,moduleおよびloadersプロパティは、outputの内部にネストされてはならず、同じレベルにある必要があります。有効な設定は次のとおりです。

module.exports = { 
    entry: './src/index.js', 
    output: { 
    path: __dirname + '/public/js', 
    filename: 'bundle.js' 
    }, 
    resolve: { 
    extensions: ['', '.js', '.jsx'] 
    }, 
    module: { 
    loaders: [ 
     { 
     test: /\.jsx?$/, 
     loader: 'babel-loader', 
     exclude: /node_modules/, 
     query: { 
      presets: ['react', 'es2015'] 
     } 
     } 
    ] 
    } 
}
