webpack config postcss hot build不起作用

Question

CLI窗口对我说：

  

您没有设置任何插件，解析器或字符串化器。现在，PostCSS不执行任何操作。在https://www.postcss.parts/上为您的案例选择插件，并在postcss.config.js

中使用它们

所以，我可以热建项目。

const buildConfig = merge(baseConfig, {
  output: {
    hotUpdateChunkFilename: "hot/hot-update.js",
    hotUpdateMainFilename: "hot/hot-update.json"
  },

    minimize: false
  },
  devtool: "inline-source-map",
  module: {
    rules: [
      {
        test: /\.ts(x?)$/,
        exclude: /node_modules/,
        use: [
          {
            loader: "babel-loader",

              babelrc: false,

          },
          {

          }
        ]
      }
    ]
  },
  devServer: {
    host: "localhost",
    port: port,
    contentBase: path.join(__dirname, DEFINES.paths.wwwroot),
    disableHostCheck: true, // host 0.0.0.0 일 경우 보안상 문제로 추가

module.exports = buildConfig;
