开启cssModules $style 为空对象

Question

webpack.config.base.js文件

const createVueLoaderOptions = require('./vue-loader.config');

const isDev = process.env.NODE_ENV === 'development';

config = {

module: {

rules: [

{

test: /\.vue$/,

loader: 'vue-loader',

options: createVueLoaderOptions(isDev)

},

{

test: /\.(gif|jpg|png|svg|jpeg)$/,

use: [{

loader: 'url-loader',

options: {

limit: 1024,

name: 'resources/[path][name].[hash:8].[ext]'

}

}]

},

{

test: /\.jsx$/,

loader: 'babel-loader'

},

{

test: /\.js$/,

loader: 'babel-loader',

exclude: /node_modules/

}

]},

mode: process.env.NODE_ENV || 'product'

}

输出的$style为 {}空对象，为什么
