Question

webpack.config.js

const styles = path.join(__dirname, "client/styles.scss");

module.exports = {
       resolve: {
          modules: [..., styles]
       }
    }

file.js

import base from "styles"; 

<div styleName="base.x">
...

</div>

以下代码摘录自我的一个webpack项目。它基本上可以编译/监视任何scss和css文件。

const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const process = require('process');


module.exports = {
    module: {
        rules: [
            // ... more
            {
                test: /\.(scss|css)$/,
                use: [
                    process.env.NODE_ENV !== 'production' ? 'style-loader' : MiniCssExtractPlugin.loader,
                    {
                        loader: "css-loader",
                        options: {
                            modules: true,
                        }
                    }, 
                    {
                        loader: "sass-loader",
                        options: {
                            data: "$env: " + process.env.NODE_ENV + ";"
                        }
                    }
                ],
            },

            // ... more
        ]
    }
}

添加您的解析配置，您应该一切顺利。但是请确保将样式的Babel转换（如果使用的话）与css-loader的localIdentName s保持同步。
