热重装无法在Nextjs 8.1应用程序中正常工作

Question

我从事Nextjs 8.1版应用程序的开发已经一年了。当我运行npm run dev命令时，应用程序以开发模式运行。当我更改一段代码并将其保存时，该应用将 重新加载 ，但更改未应用。

这是我的 package.json 文件内容：

        "optimize-css-assets-webpack-plugin": "^5.0.3",
        "poststylus": "^1.0.0"
    }
}

这是 next.config.js 文件：

const withCss = require('@zeit/next-css'); // used to load css files
const withStylus = require('@zeit/next-stylus'); // used to load stylus files
const withImages = require('next-images'); // used to load local images
const OptimizeCSSAssetsPlugin = require('optimize-css-assets-webpack-plugin'); // used to minimize the compiled css file in production mode

module.exports = {
    ...withStylus(
        withCss(
            withImages(
                {
                    cssLoaderOptions: {
                        url: false
                    },
                    // production config to minimize the compiled css file
                    webpack(config) {
                        if (config.mode === 'production') {
                            if (Array.isArray(config.optimization.minimizer)) {
                                config.optimization.minimizer.push(new OptimizeCSSAssetsPlugin({}));
            
                            }
                        }
                        return config;
                    }
                }
            )
        )
    ),
    env: {
        /*
         * api route and website route in production and development mode
         * you should use build dev routes in development mode and for nightly version
         * and use the master build routes for production mode and master build for main server
         */
        //dev build
         apiRoute: 'https://nightly.karan.ir',
         websiteRoute: 'https://nightly.karan.ir',
         useTagManager: false,

         // for master build
        //  apiRoute: "https://karan.ir",
        //  websiteRoute:  "https://karan.ir",
        //  useTagManager: true,

        // this value is used to determine which environment is active to active firebase cloud messaging or not
        enableFireBase: 'false'
    }
};

如果我在终端中按Ctrl + C，然后再次运行npm run dev，则所有更改都将应用。
