问题描述
我在 docker 中有一个带有 Ruby on Rails 6、Webpacker 和 react-rails 的容器,当我重新加载页面时,它的编译延迟超过 20 秒,所以我想为我的项目添加热重新加载,但它只是不起作用. webpack-dev-server 运行良好,但页面没有更新更改。
我正在使用 foreman 运行 bin/webpack-dev-server 和 rails server,我正在使用 react-refresh-webpack-plugin 来刷新 react。当我更改代码时,即使我重新加载页面,页面也不会收到更改。

解决方法
我可以解决它,webpack 没有监视我的文件,我在 webpacker.yml 的 watch_options 中添加了 aggregateTimeout: 300 和 poll: 500,并且它起作用了。
