老师，这是我在webpack.config.js中的配置：           

     test: /\.(png|gif|jpg|svg)$/i,

                use: [

                    {

                        loader: 'url-loader',

                        options: {

                            name: 'assets/[name]-[hash:5].[ext]',

                            limit: 20000

                        }

                    },

                    {

                        loader: 'image-webpack-loader',

                        options: {

                            bypassOnDebug: true

                        }

                    }

                ]

命令行运行webpack报错如下：

查了半天没找到原因？？
