在使用extract-text-webpack-plugin插件遇到了问题，在开发环境编译没问题，在生产环境编译出问题了，

cross-env NODE_ENV=production webpack --progress --hide-modules --config ./build/webpack.client.conf.js

经代码排查，发现是缺少使用ExtractTextPlugin注入到某个地址里面去

if (process.env.NODE_ENV === 'production') {
    clientConf.plugins.push(
        new ExtractTextPlugin({
            filename: utils.assetsPath('css/[name].[contenthash].css')
        })
    )
}

之前只是在utils函数里面有这个使用

 return ExtractTextPlugin.extract({
        use: loaders,
        fallback: 'vue-style-loader'
})

缺少在webpack.client.conf.js使用
