我正试图解决这个问题，但我想不出代码

当nodemon进程突然结束/关闭终端时发生。通常使用不同的端口号或重新启动系统。通过运行以下命令，可以终止在端口3000上运行的nodemon进程：

kill -9 $(lsof -t -i:3000)

错误显示端口已在使用中，似乎您正在端口3000上运行另一个应用程序。有几次我必须更改端口及其工作！！很高兴听到它现在对你有效，当你再次遇到这个问题时，我建议你注销/重新启动机器，如果它一直对我有效。我会这样做的！谢谢错误显示端口已在使用中，似乎您正在端口3000上运行另一个应用程序。有几次我不得不更改端口及其工作！！很高兴听到它现在对你有效，当你再次遇到这个问题时，我建议你注销/重新启动机器，如果它一直对我有效。我会这样做的！非常感谢。
