导读：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.我尝试过一次不同的端口,但是从那时起,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. /Users/colmtuite/.rvm/ge

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.我尝试过一次不同的端口,但是从那时起,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.

当我运行ps aux | grep rails我得到这个输出：

colmtuite        6422   0.0  0.0  2441988    668 s002  S+    2:44am   0:00.00 grep rails

当我运行ps aux | grep ruby??我得到这个输出：

colmtuite       13305   0.0  0.0  2423356    200 s000  R+    8:15pm   0:00.00 grep ruby

我的港口出于某种原因关闭了吗？

解决方法

我也有同样的问题

这适合我

$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
