Eventmachine start_tcp_server没有接受者 – 端口正在使用或需要root权限（RuntimeError）
我现在无法运行我的本地服务器3天了。 重新启动计算机没有帮助。 有几次，经过反复尝试大约40-50次，它随机工作 – 我无法弄清楚为什么。 我尝试了一次不同的端口，但是从那以后，没有端口工作。 每次我尝试运行我的rails服务器时都会得到这个。

我的港口出于某种原因关闭了吗？
我也有同样的问题
这对我有用
$ ps ax | grep rails
然后使用进程ID杀死进程
$ kill -9 [process Id]
..
例
$ kill -9 20496
..
再次启动服务器
