Npm Run Serve Not Running the Project in React Js with Webpack Environment

I'm trying to route some component in react js. So I install npm install serve --save-dev. After I run this comment "

npm run serve

I'm getting some errors.

Here my package file.

Here my web packs file

    var webpack = require('webpack');
var path = require('path');

var BUILD_DIR = path.resolve(__dirname, 'public');
var APP_DIR = path.resolve(__dirname, 'src');

var config = {
  entry: APP_DIR + '/index.jsx',
  output: {
    path: BUILD_DIR,
    filename: 'bundle.js'
  },
  module : {
    Loaders: [
      {
        test : /\.jsx?/,
        include : APP_DIR,
        loader : 'babel-loader'
      }
    ]
  }
};

module.exports = config;
