was css,CSS独立打包报错Chunk.entry was removed. Use hasRuntime() 是什么原因？

麻烦大家帮我解决。。我的webpack.config.js是在项目根目录有一个，在特定的功能文件夹一个，打包时候，在根目录运行webpack命令，js文件里面引入X文件夹的另一个webpack.config.js,这样我可以通过切换文件夹路径决定打包哪个模块。

!!!!下面是X文件夹里面的config

const webpack = require('webpack');

const filePath = './BehaviorHabit/src/main/webapp/resources/wx/js/assessPage_demo';

var ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {

// devtool: 'cheap-module-eval-source-map',

entry: {

'./BehaviorHabit/src/main/webapp/resources/wx/js/common/commonPlugins': ["jquery", "jquery.mmenu", "react", "react-dom"],

'./BehaviorHabit/src/main/webapp/resources/wx/js/assessPage_demo/dist/bundle': filePath + '/js/assessEntry.js'

},

output: {

filename: '[name].js'

},

module: {

loaders:[

{

test: /\.js|js[x]?$/,

exclude: /node_modules/,

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

loader:"babel"

// loader: 'babel-loader?presets[]=es2015&presets[]=react',

},

// {

// test: /\.css$/,

// // modules&localIdentName=[local] 加上modules表示使用css模块化 、

// // localIdentName是对css命名,[name]模块(文件)名 [local]类名 [hash:base64:5] hash值

// loader: 'style!css?modules&localIdentName=[local]'

// // &localIdentName=[name]localIdentName=[name]__[local]___[hash:base64:5]

// // loader: 'style-loader!css-loader'

// },

{

test: /\.css$/,

loader: ExtractTextPlugin.extract("style-loader", "css-loader")

},

// {

// test: /\.(png|jpg)$/,

// loader: 'url-loader?limit=8192'

// },

{ test: /\.(gif|jpg|png|woff|svg|eot|ttf)\??.*$/, loader: 'url-loader?limit=50000&name=[path][name].[ext]'}

]

},

plugins: [

new webpack.optimize.CommonsChunkPlugin({

name: ['./BehaviorHabit/src/main/webapp/resources/wx/js/common/commonPlugins', './BehaviorHabit/src/main/webapp/resources/wx/js/common/manifest'],

minChunks : Infinity

}),

new webpack.optimize.UglifyJsPlugin({

compress: {

warnings: false

}

}),

new webpack.ProvidePlugin({

"React": "react",

"ReactDOM": "react-dom",

$ : "jquery",

}),

new ExtractTextPlugin("./style.css"),

],

};

!!!这里是根目录的config cfg就是上面的X文件夹的config.js 就是上面那段代码

const webpack = require('webpack')

var ExtractTextPlugin = require('extract-text-webpack-plugin');

var cfg = require('./BehaviorHabit/src/main/webapp/resources/wx/js/assessPage_demo/webpack.config.js');

module.exports = {

// devtool: 'cheap-module-eval-source-map',

entry: cfg.entry,

output: cfg.output,

module: cfg.module,

plugins: cfg.plugins

};

运行webpack后报错是Chunk.entry was removed. Use hasRuntime() ，请问这是什么原因？找了很久找不到答案。。请问大神这个报错应该怎么解决T T

ps: style-loader css-loader extract-text-webpack-plugin这些都已经install了。。。
