我试图使用webpack v5实现热模块替换(HMR),但它不起作用。当我修改并保存一个文件时,webpack会正确重新编译项目,但前端页面不会更新。
我阅读了这篇文章并按照说明操作:https://webpack.js.org/guides/hot-module-replacement/ 这是我的webpack配置:

我使用以下工具:
- webpack 5.7.0
- webpack-cli 4.2.0
- react 16.13
- node 14.15.1
- npm 6.14.8
我使用以下命令启动webpack: webpack serve --host 0.0.0.0 --config config/webpack.dev.js
我做错了什么?感谢您的帮助。:)
