Question

我在webpack中遇到问题，我尝试使用ant设计...但是当应用程序运行时...出现如下错误，请帮助我谢谢。我曾尝试通过Google搜索但找不到正确的方法回答

此文件webpack.config.js

const path = require("path");

module.exports = {
  entry: { main: "./src/index.js" },
  mode: "development", // "production" | "development" | "none"
  output: {
    path: path.resolve(__dirname, "./wwwroot/dist"), // string
    // the target directory for all output files
    // must be an absolute path (use the Node.js path module)
    filename: "bundle.js", // the filename template for entry chunks
    publicPath: "dist/" // string    // the url to the output directory resolved relative to the HTML page
  },
  resolve: {
    extensions: [".js", ".jsx"]
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
          options: {
            plugins: ["react-hot-loader/babel"]
          }
        }
      },

      {
        test: /\.s[ac]ss$/i,
        use: [
          // Creates `style` nodes from JS strings
          "style-loader",
          // Translates CSS into CommonJS
          "css-loader",
          // Compiles Sass to CSS
          "sass-loader"
        ]
      },
      {
        test: /\.(png|woff|woff2|eot|ttf|svg|jpg)$/,
        loader: "url-loader?limit=100000"
      }
    ]
  }
};

此文件.babelrc

        "helpers": true,
        "regenerator": true,
        "useESModules": false

如何解决以上图片错误？我的webpack有什么问题？

Answer 1

看起来您的正则表达式/\.s[ac]ss$/i仅捕获scss和sass扩展名。请看一下：https://webpack.js.org/guides/asset-management/#loading-css为CSS文件添加规则。如果要使用同一规则捕获scss，sass和css，请使用此/(\.css|\.scss|\.sass)$/
