为什么CSS单独打包的时候生成不了文件夹~？？？ webpack是成功的

Question

var webpack = require('webpack');var ExtractTextPlugin = require('extract-text-webpack-plugin');var config = {entry: {'common': ['./src/page/common/index.js'],'index' : ['./src/page/index/index.js'],'login' : ['./src/page/login/login.js']},output: {path: __dirname + '/dist',filename: 'js/[name].js'},externals : {'jquery' : 'window.jQuery'},module: {loaders: [{ test: /\.css$/,loader: ExtractTextPlugin.extract("style-loader!css-loader") }]},plugins: [new webpack.optimize.CommonsChunkPlugin({name : 'common',filename : 'js/base.js',// minChunks: Infinity}),new ExtractTextPlugin("dist/css/[name].css"),]};module.exports = config;
