我实际上正在做有关如何设置超级账本多组织网络的粗略课程.

I am actually doing a udemy course about how to setup a hyperledger multi org network.

推荐答案

错误显示端口3000繁忙.

EADDRINUSE表示该端口上已经在运行某些进程.

EADDRINUSE means some process is already running on that port.

您可以使用以下命令找到该过程:

You can find the process by using the following command:

sudo ss -lptn 'sport = :3000'

它将返回您的进程ID，然后您可以通过以下方式将其杀死:

It will return you process id, then you can kill it by:

sudo kill -9 process_id
