您已经有一个进程正在侦听端口 3000（mongrel 的默认端口）。
尝试一下：
看看是否会出现类似的错误。
如果您尝试安装多个 Rails 应用程序，则需要将每个 mongrel 分配给单独的端口并相应地编辑 apache conf。
如果您不想这样做，杀死所有杂种的最直接方法是打开 Windows 任务管理器并杀死所有“ruby”进程。
请注意，如果您将 mongrel 安装为自动启动的服务
...ruby 进程将自动重新生成。 在这种情况下，您必须通过 Windows 服务面板编辑进程属性。 如果您需要更多信息，请告诉我。
You already have a process listening on port 3000 (the default port for mongrel).
Try:
and see whether you get a similar error.
If you're trying to install more than one Rails app, you need to assign each mongrel to a separate port and edit you apache conf accordingly.
If you not trying to do that, the most direct way of killing all mongrels is to open windows task manager and kill all the 'ruby' processes.
Note that if you have mongrel installed as a service that starts automatically
...the ruby process will regenerate automatically. In that case, you'll have to edit the process properties through the windows services panel. Let me know if you need more info.
在 Windows 上，我找到了两种可能的方法来解决此问题：
On Windows, I found two possible ways for fixing this issue:
我自己不在 Windows 上使用 mongrel，但我猜这个错误相当于 Linux 的“端口正在使用”错误。 您是否正在尝试将服务器绑定到其他设备已经在侦听的端口？
I don't use mongrel on windows myself, but I guess that error is the equivalent of Linux' "port in use" error. Are you trying to bind the server to a port where something else is already listening?
