Webpack mini-css-extract-plugin在捆绑过程中不包括我的scss

Question

我有一个React应用程序，我试图在其中包含一些Sass。
我还使用Webpack将所有.scss文件捆绑到一个.css文件中进行生产。
为此，我使用了mini-css-extract-plugin，但是我的所有样式文件都没有捆绑到最终输出文件中，即使它们已导入下面的app.js中也是如此。仅将我app.js中的.scss文件正确地装入了捆绑包，但没有正确地装入了styles.scss。因此，我的样式在开发阶段有效，但在部署生产时却没有。

这是我要构建我的应用程序时运行的命令（在package.json文件中）。

module.exports = merge(common, {
  mode: 'production',
  devtool: 'source-map',
  optimization: {
    minimizer: [
      new UglifyJsPlugin({
        cache: true,
