index.css代码：

body{
    background: url('../../image/test-img.jpg');
}

module配置：

module: {
        loaders: [
            {test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader", "css-loader")},
            // {test: /\.(gif|png|jpg)\??.*$/, loader: 'url-loader?limit=100&name=resource/[name].[ext]'}
            { test: /\.(gif|png|jpg|woff|svg|eot|ttf)\??.*$/, loader: 'url-loader?limit=100&name=resource/[name].[ext]' }
        ]
    },

后报错

尝试把url-loader后面的内容删掉就build成功，求解？
