@小鱼报错内容和上面的一样

小鱼

@shawn 在运行驱动雷达时候报错中说：

退出

退出后再进来试试

@小鱼
1）退出后不重启小车直接输入 xhost + && sudo docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged -v /tmp/.X11-unix:/tmp/.X11-unix --device /dev/snd -e DISPLAY=unix$DISPLAY -p 8889:8888 registry.cn-hangzhou.aliyuncs.com/fishros/fishbot_laser
选择2后终端报：
sk@sk-virtual-machine:~$ xhost + && sudo docker run -it --rm -v /dev:/dev -v /dev/shm:/dev/shm --privileged -v /tmp/.X11-unix:/tmp/.X11-unix --device /dev/snd -e DISPLAY=unix$DISPLAY -p 8889:8888 registry.cn-hangzhou.aliyuncs.com/fishros/fishbot_laser

2）小车重启后输入命令，直接选择2.驱动雷达，终端报：

报上面相同错误

小鱼

@shawn nc -l 8889 有数据流吗

shawn

@小鱼没有数据流，只有在小车重启后输入会有招呼语
