fix.sh

1. 查找占用 18789 端口的进程

$ lsof -i :18789 # macOS / Linux

$ netstat -ano | findstr 18789 # Windows

2. 方案 A — 终止冲突进程

$ kill -9 <PID>

# Then restart OpenClaw

$ docker compose up -d

3. 方案 B — 更改 OpenClaw 端口

# docker-compose.yml

services:

openclaw:

ports:

可以。修改 docker-compose.yml 映射左侧即可。
