composer-rest-server未处理的'错误'事件

Question

当我尝试composer-rest-server -c acme-admin@test-bna时，我得到了这个输出：

Error: listen EADDRINUSE :::3000
    at Server.setupListenHandle [as _listen2] (net.js:1360:14)

我实际上正在做一个关于如何设置超级多组织网络的课程。

Answer 1

错误显示端口3000正忙。

EADDRINUSE意味着某个进程已在该端口上运行。

您可以使用以下命令找到该过程：

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：

sudo kill -9 process_id

Answer 2

问题是某个进程在端口3000上运行。此命令修复了它。

fuser -n tcp -k 3000
