sass-загрузчик не генерирует CSS

Я попытался обновить эту конфигурацию веб-пакета, чтобы сгенерировать css из scss. Я добавил styles.scss в src папку с одним правилом CSS: 

body{
  font-size: 38px;
}

Если я запускаю yarn build или yarn dev, webpack не создает никаких файлов CSS, и я не получаю никакой ошибки.

webpack.config.js 

/* global __dirname, require, module*/

const webpack = require('webpack');
const path = require('path');
const env = require('yargs').argv.env; // use --env with webpack 2
const pkg = require('./package.json');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

let libraryName = pkg.name;

let outputFile, mode;

if (env === 'build') {
  mode = 'production';
  outputFile = libraryName + '.min.js';
} else {
  mode = 'development';
  outputFile = libraryName + '.js';
}

const config = {
  mode: mode,
  entry: __dirname + '/src/index.js',
  devtool: 'inline-source-map',
  output: {
    path: __dirname + '/lib',
    filename: outputFile,
    library: libraryName,
    libraryTarget: 'umd',
    umdNamedDefine: true,
    globalObject: "typeof self !== 'undefined' ? self : this"
  },
  module: {
    rules: [
      {
        test: /(\.jsx|\.js)$/,
        loader: 'babel-loader',
        exclude: /(node_modules|bower_components)/
      },
      {
        test: /(\.jsx|\.js)$/,
        loader: 'eslint-loader',
        exclude: /node_modules/
      },
      {
        test: /\.scss$/,
        use: [
            // fallback to style-loader in development
            process.env.NODE_ENV !== 'production' ? 'style-loader' : MiniCssExtractPlugin.loader,
            "css-loader",
            "sass-loader"
        ]
    }
    ]
  },
  resolve: {
    modules: [path.resolve('./node_modules'), path.resolve('./src')],
    extensions: ['.json', '.js', '.scss']
  },
  plugins: [
    new MiniCssExtractPlugin({
        // Options similar to the same options in webpackOptions.output
        // both options are optional
        filename: "[name].css",
        chunkFilename: "[id].css"
    })
]
};

module.exports = config;

Проверьте, импортировали ли вы scss файл в файле записи js, например index.js.
