如何在js代码（nodejs服务器）中获取SCSS变量？

Question

从这个blogpost示例https://til.hashrocket.com/posts/sxbrscjuqu-share-scss-variables-with-javascript中，我试图在js代码中获取scss变量，但没有成功。

index.js文件

import variables from './variables.scss';
console.log(variables);

variables.scss文件

$myvar: 100;

:export {
  myvar: $myvar;
}

webpack.config.js文件

module.exports = {
  mode: 'development',
  module: {
    rules: [{
        test: /\.scss$/,
        use: [{
          loader: "style-loader"
        }, {
          loader: 'css-loader'
        }, {
          loader: 'sass-loader'
        }]
    }]
  }
};

  "dependencies": {
    "css-loader": "^5.0.2",
    "lodash": "^4.17.20",
    "postcss-loader": "^5.0.0",
    "sass": "^1.32.6",
    "sass-loader": "^11.0.1",
    "style-loader": "^2.0.0",
    "webpack": "^5.21.2",
    "webpack-cli": "^4.5.0"
  }

多谢帮忙。

我没有意识到这一点，但也许这只适用于“CSS模块”。如果不将css-loader配置为基于模块，我从未尝试过。（您可以在此答案中的“我的配置”中看到模块已激活）请尝试以下操作：将variables.scss重命名为variables.module.scss，因为默认情况下，css-loader将根据文件名（https://webpack.js.org/loaders/css-loader/#modules)将您的文件视为模块或不视为模块。
