如何正确应用 sass 加载器来应用样式

Question

我正在一个项目中使用多个 sass 文件并将它们调用到一个文件中，问题是当我尝试应用样式时它们没有显示出来。 sass files。现在这就是我配置 webpack.config.js 文件的方式

const path = require("path");

module.exports = {
  mode: "development",
  entry: "./src/index.js",
  output: {
    filename: "main.js",
    path: path.resolve(__dirname, "dist"),
    assetModuleFilename: "images/[hash][ext][query]",
  },

  devtool: "inline-source-map",
  devServer: {
    contentBase: "./dist",
  },
  module: {
    rules: [
      {
        test: /\.(s[ac]|c)ss$/i,
        use: [
          // Creates `style` nodes from JS strings
          "style-loader",
          // Translates CSS into CommonJS
          "css-loader",
          // Compiles Sass to CSS
          "sass-loader",
        ],
      },
      {
        test: /\.(png|svg|jpg|jpeg|gif)$/i,
        type: "asset/resource",
        generator: {
          filename: "static/[hash][ext][query]",
        },
      },
    ],
  },
};

这是我得到的错误

这就是我将样式导入项目的方式

import "../sass/main.scss";

我无法将我的样式应用到项目中，我整天都在尝试解决这个问题，但没有成功，如果有人能指出正确的方向，我将不胜感激。

你的 Webpack 配置是正确的。你的错误

$font-dancingScript: "跳舞脚本"，草书；

添加'必须解决您的问题；

$font-dancingScript: ' "舞蹈脚本", cursive ';

配置：

  {
    test: /\.css$/,
    use: ["style-loader", "css-loader"],
  },
  {
    test: /\.s[ac]ss$/i,
    use: ["style-loader","css-loader","sass-loader"],
  }
