为什么'；是否在输出文件夹中提取文本网页包插件创建app.css？

我正在尝试使用extract text webpack插件在我的输出文件夹中生成app.css（在我的条目js中，我正在导入scss）

我看到了：

这实际上很有帮助，因为如果我使用完整路径作为我的公共路径，那么它可以工作，但这意味着出于某种原因，extract text webpack插件不能工作

我的配置：

'use strict';

var webpack = require('webpack');
var autoprefixer = require('autoprefixer');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var ngAnnotatePlugin = require('ng-annotate-webpack-plugin');


module.exports = function makeWebpackConfig (options) {

    var BUILD = !!options.BUILD;

    var config = {};

    config.entry = {
        app: './app.js',
        iosCordova: ['./static/wrapper/js/ios/cordova_all.min.js'],
        androidCordova: ['./static/wrapper/js/android/cordova_all.min.js']
    };

    config.output = {
        path: __dirname + '/_dist',

//the commented out works without generating an app.css in output
        //publicPath: BUILD ? 'http://danny.il.corner.com:2222/' : 'http://danny.il.corner.com:8080/',
        publicPath: BUILD ? '/' : 'http://danny.il.corner.com:8080/',

        filename:  '[name].bundle.js',

        chunkFilename:  '[name].bundle.js'
    };

    if (BUILD) {
        config.devtool = 'source-map';
    } else {
        config.devtool = 'eval';
    }

    config.module = {
        noParse: /node_modules\/html2canvas/,
        preLoaders: [],
        loaders: [
            {

                query: {

                ]
            },
            {
                test: /\.(png|jpg|jpeg|gif|svg|woff|woff2|ttf|eot)$/,
                loader: 'file?name=[name].[ext]'
            }, {
                test: /\.html$/,
                loader: "ngtemplate?relativeTo=" + __dirname + "!raw"
            }
            ,
            {
                test: /\.(css)$/,
                loader: ExtractTextPlugin.extract('style-loader', 'css-loader!postcss-loader')

                loaders: ["style", "css?sourceMap", "sass?sourceMap"]
            }
        ]
    };

    config.postcss = [
        autoprefixer({
            browsers: ['last 3 versions']
        })
    ];
    config.plugins = [

        new webpack.ProvidePlugin({

            jQuery: "jquery",
            "window.jQuery": "jquery"
        })
        ,
        new ngAnnotatePlugin({
            add: true
        })
    ];

    config.plugins.push(
        new HtmlWebpackPlugin({
            template: './index.html',
            inject: true,
            excludeChunks: ['app','iosCordova','androidCordova']
        })
    );

    if (BUILD) {
        config.plugins.push(

            new webpack.NoErrorsPlugin(),

            new webpack.optimize.DedupePlugin(),

            new webpack.optimize.UglifyJsPlugin()
        )
    }

    config.devServer = {
        stats: {
            modules: false,
            cached: false,
            colors: true,
            chunk: false
        }
    };

    return config;
};

谢谢你的帮助：）
