Starting MailCatcher
~~> ERROR: Something's using port 1025. Are you already running MailCatcher?

然后当我尝试使用http://localhost:1080/向我展示app mailcatcher时。 但是我需要做什么才能使应用程序不再显示此错误？

1 个答案:

答案 0 :(得分：2)

似乎在该端口上运行了一些东西。它可以是mailcatcher的另一个实例，或者其他一些进程。

在大多数* nix系统上，您可以使用以下命令搜索占用特定端口的进程：

lsof -i :PORT

例如：

lsof -i :1025

结果将包含PID（进程ID）。你可以用这个来杀死违规的过程。

kill -9 SOME_PID

示例：

kill -9 32487
