安装jQuery会导致webpack错误

这是我的webpack.config.js:

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

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

var node_dir = __dirname + '/node_modules';

var cOnfig= {
	entry: {
	  app: APP_DIR + '/index.js',
	  common: ["jquery"],
	},
	output: {
		path: BUILD_DIR,
		filename: 'bundle.js'
	},
	resolve: {
		// This is so that you don't have to write the file extension while importing it.
		// Instead of import HomeComponent from './HomeComponent.jsx'
		// you can do import HomeComponent from './HomeComponent'
		extensions: ['.js', '.jsx','.json', '*'],
		alias: {
      'jquery': node_dir + '/jQuery/src/wrapper.js',
    },
	},
	externals: {
    jquery: 'jQuery'
  },
	plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      name: "common",
      filename: "common.js",
      minChunks: Infinity,
    }),
    new webpack.ProvidePlugin({
      $: "jquery",
      jQuery: "jquery",
      jquery: "jquery",
      "window.jQuery": "jquery",
    }),
  ],
	module: {
    loaders : [
			{
				test : /\.jsx?/,
				include : APP_DIR,
				exclude: /node_modules/,
				loader : 'babel-loader'
			}
		],
	},
};

module.exports = config;
