我的软件版本是22.04的ubuntu，装的是humble版ros2。在按9章第三节的上述命令后，出现了discarding message的提示。在地图中 没有出现激光点云。如图界面所示

@vico1999 请看新版教程：https://fishros.com/d2lros2foxy/#/chapt10/10.5配置Fishbot进行建图

建图在第十章

[vico1999]

@小鱼 用新的章节内容后，也还是没有 正常启动。报的错误和之前一样

[小鱼]

@vico1999 重新编译source即可

[vico1999]

@小鱼 source 了以后不行，我是把报错所需要的文件夹，复制到提示找不到的目录后解决的
