SSH到狗上面运行这个
ros2 run rqt_console rqt_console
会报错
Package 'rqt_console' not found

把狗加入一个局域网,同样使用ROS_DOMAIN_ID=42,结果ros2 multicast receive和ros2 multicast send是互通的,但是两个机器的节点和消息就是不通,没法调试程序啊.

请指点怎么样调试代码看日志!

日志可以直接查看/var/log/syslog文件，在实时刷。或者也可以journalctl -fn 100000 |grep 程序名，关于journalctl更多的用法可以搜索到详细的教程。
