React - 模块解析失败：您可能需要适当的加载程序来处理此文件类型

Question

请帮我解决这个问题

const path = require（＆＃39; path＆＃39;）; // const HtmlWebPackPlugin = require（＆＃34; html-webpack-plugin＆＃34;）;

module.export = {
entry:'./src/index.js',
output:{
    path: path.resolve(__dirname, "build"),
    filename: 'bundle.js'
},
module: {
loaders: [{
  test: /\.(js|jsx)?$/,
    exclude: /node_modules/,
    loader: 'babel-loader',

    query: {
       presets: ['es2015', 'react']
    }
}]
},

devServer: {
    port: 8000,
    contentBase: 'build',
    inline: true,
    mode: 'development'
},

}
