extract-text-webpack-plugin输出css文件，图片路径错误？

Question

When I use extract-text-webpack-plugin output css file into a folder, the image url is wrong, my webpack config is below:

"use strict";
var path = require('path');
var webpack = require('webpack');

// webpack plugins
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');


module.exports = {
    entry: path.resolve(__dirname, 'app/scripts/main.js'),
    output: {
        path: path.resolve(__dirname, "build"),
        //publicPath: path.resolve(__dirname, "build"),
        filename: 'js/[name]-[hash].js'
    },
    module: {
        loaders: [{
                test: /\.jsx?$/,   
                loader: 'babel',    
                exclude: /(node_modules|bower_components)/,
                query: {
                    presets: ['react', 'es2015']
                }
        },{
                test: /\.scss$/,
                exclude: /(node_modules|bower_components)/,
                loader: ExtractTextPlugin.extract('style', 'css!sass!postcss')
        },{
                test: /\.css$/,
                exclude: /(node_modules|bower_components)/,
                loader: ExtractTextPlugin.extract('style', 'css!postcss')
        },{
                test: /\.(woff|woff2|svg|eot|ttf)/,
                loader: 'url?prefix=font/&limit=10000'
        },{
                test: /\.(png|jpe?g|gif|svg)$/,
                loaders: [
                    'file?name=images/[name].[ext]',
                    //'image-webpack'
                ]
            }
        ]
    },

    // image handle
    // imageWebpackLoader: {
    // progressive: true,
    // optimizationLevel: 3,
    // interlaced: false,
    // pngquant: {quality: "65-70", speed: 4}
    // },

    postcss: [
        require('autoprefixer')
    ],

    plugins: [
        new webpack.BannerPlugin('This file is created by yugasun'),
        new HtmlWebpackPlugin({
            title: 'RedChild',
            template: __dirname + '/app/template/index.tmpl.html'
        }),
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.optimize.UglifyJsPlugin(),
        new ExtractTextPlugin('css/[name]-[hash].css')
    ]
};

my output 'build' folder tree like this:

.
├── css
│   └── main-72c33a6c0ad73a5a0403.css
├── images
│   ├── arrow.png
|   |.....
│   └── wrong_title.png
├── index.html
└── js
    └── main-72c33a6c0ad73a5a0403.js

But in my output css file the image url is 'images/arrow.png', what I want is like '../images/arrow.png'.

Then I add the extract-text-webpack-plugin options like below:

Change:

new ExtractTextPlugin('css/[name]-[hash].css')

To:

new ExtractTextPlugin('css/[name]-[hash].css', {
            publicPath: '../'
        })

But the parameter 'publicPath' doesn't work, in my output css file the image url is still 'images/arrow.png'.

Answer 1

Why don't you use output.publicPath which actually specifies the public url of your output files? This works for me well.
