Ruby on Rails服务器未启动

Question

我一直在尝试使用命令Rails服务器运行我的Rails应用程序，但是最近出现了此错误：

我可以通过指定其他端口来解决此问题，即使用命令“

导轨服务器-p 4000

”，但我想使用以前的部署方式。我该如何解决？

附言：我是Rails的新手，请简单说明。：p非常感谢你们！谢谢！

这意味着3000端口不是空闲的。您的项目的另一个实例已经在使用它。因此，通过以下命令找到该进程：

lsof -i :3000

并通过以下方法终止该过程：

kill -9 processid

您还可以从应用程序的temp文件夹中删除进程ID。
或者，您可以通过以下命令在其他端口上启动应用程序rails s -p 3001
