PostCSS不加载SCSS模块依赖项

Question

嘿堆高车，

我正在使用 Rails 和 Webpacker 构建一个 React 应用，这迫使我使用PostCSS来加载样式以及其他可选样式顶部的装载机。

从我的import '@material/react-button/index';之类的包中导入 SCSS 模块时， PostCSS 似乎并没有加载它们各自的依赖项，因为它需要@material/base/mixins装载。

node_modules/@material/base/_mixins.scss文件夹中存在文件node_modules。因此，我真的不知道为什么它不会读取或导入相应的文件。

Environment.js

const { environment } = require('@rails/webpacker')
const path = require('path')

module: {
  rules: [{
    test: /\.js(\.erb)?$/,
    exclude: /node_modules/,
    loader: 'babel-loader',
    options: {
      presets: [
        ['env', { modules: false }]
      ]
    }
  },
  {
    test: /\.scss$/,
    use: extractSCSS.extract({
      use: [
      { loader: 'style-loader', options: { sourceMap: true } },
      { loader: 'css-loader', 
          options: { 
            sourceMap: true,
            importLoaders: 2 
          } 
      },
      { loader: 'postcss-loader', options: { sourceMap: true } },
      { loader: 'sass-loader', 
          options: { 
            sourceMap: true, 
            includePaths: ["node_modules"]
          }
      }]
    })
  }]
}

module.exports = environment
