Question

请参阅以下文件以供参考。在为react demo项目创建设置时，我无法启动npm start命令。

**package.json**
{
  "name": "package.json",
  "version": "1.0.0",
  "description": "Demo application",
  "main": "index.js",
  "scripts": {
   "start": "webpack-dev-server --hot"
  },
  "author": "Abhishek",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2"
  }
}

Webpack.config.js

var config = {
   entry: './main.js',

   output: {
      path:'./',
      filename: 'index.js',
   },

   devServer: {
      inline: true,
      port: 8080
   },

   module: {
      loaders: [
         {
            test: /\.jsx?$/,
            exclude: /node_modules/,
            loader: 'babel',

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

module.exports = config;

当我运行npm.start时，请找到以下日志

18 error You can get information on how to open an issue for this project with:
18 error     npm bugs package.json
18 error Or if that isn't available, you can get their info via:
18 error
18 error     npm owner ls package.json
18 error There is likely additional logging output above.
19 verbose exit [ 1, true ]

请帮助解决此错误。提前谢谢。
