webpack-dev-server的备用端口

Question

我使用webpack-dev-server运行一个Electron项目，并使用JBoss / Wildfly服务器运行一个Web服务。两者都在端口8080上运行。首先运行Wildfly服务器，然后运行webpack-dev-server，将在Electron窗口中从内部的Wildfly默认页面开始运行。

作为解决方案，我更改了端口webpack-dev-server的运行状态，如建议的here一样，webpack-dev-server --hot --host 0.0.0.0 --port 9000 --config=./webpack.dev.config.js --mode development，但错误仍然存​​在。

here的另一种解决方案建议将port: 9000添加到Webpack配置文件中，但是这种方法也仍然存在错误。

我应该怎么做才能在8080以外的其他端口上运行webpack-dev-server？
