无法启动webbrick - TCPServer错误:地址已在使用中

Question

我收到以下错误:

重新启动我的机器后,我仍然遇到这个问题.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(stat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.

尝试运行lsof | grep 3000然后kill -9 <number of process> 如果它没有帮助,尝试运行rails服务器并-p 3001选择更改端口
