我收到以下错误：

重新启动机器后，我仍然遇到此问题。我已经使用Rails查看了TCPServer错误的其他SO帖子。

ps -eo pid,ppid,user,args,stat

不返回rails的结果

ps aux

不返回任何Zombie Processes（统计列中的Z）或Rails服务器。

这对我来说很奇怪，因为一切都很好。我切换了一个gemset，重新安装了Rails 3.1.1，现在我无法运行它。

Answer 1

尝试运行lsof | grep 3000，然后kill -9 <number of process> 如果它没有帮助，请尝试使用-p 3001选项运行rails服务器以更改端口

Answer 2

嗯，我知道回答很晚，但就在同一天我遇到了同样的问题。

我所做的就是，重启我的机器。似乎其他应用程序使用相同的端口！..

所以，只需重新启动，问题就解决了！
