ros版本：humble
操作步骤：在～目录下的终端里输入了rqt-humble-rqt-tf-tree -y和rqt-$ROS_DISTRO-rqt-tf-tree -y

自我尝试：
1.在输入该命令之前尝试了sudo apt update, sudo apt-get update, sudo apt upgrade, sudo apt clean等系列apt操作，但依然报错
2.用各种方式换了镜像源，测试了更换后的镜像源可以用后，还是报错
3.换到网络更好一点的地方，还是报错
4.重启电脑后再次尝试，还是报错

纯小白，不太懂这些描述够不够准确，后续我还会继续自己尝试，希望有大佬指点一下尝试方向，谢谢

如题所示;
书籍中的5-15的代码中的transform.transform.translation.y的值是否存在错误;
书上y值赋值为0.0，但是5.2小结开头的camera_link相对于bottle_link的平移分量y为0.3；
y值是不是应该是0.3，还是说有其他转换，希望能被解答下疑惑

本人是一个ros2萌新1，刚刚在wsl2上面用鱼香ros一键安装了jazzy版的ros2，但是用ros2 run demo_nodes_cpp listener命令和ros2 run demo_nodes_cpp talker命令时，talker可以正常呼出，但是listener接受不了55555...这该怎么办呀
而且小海龟也动不了，这是不是通信方面的问题呢

Ubuntu版本20.04，ROS2版本foxy。如题，按照视频中代码输入后编译正常，运行前也进行了source，运行时报错chihaya@chihaya-virtual-machine:~/chapt5/chapt5_ws$ ros2 run demo_cpp_tf tf_listener
terminate called after throwing an instance of 'std::runtime_error'
what(): Node has already been added to an executor.
询问deepseek的解决方法是删除(*buffer_,this)中的this，但是删除后只会输出警告Warning: Invalid frame ID "base_link" passed to canTransform argument target_frame - frame does not exist
at line 133 in /tmp/binarydeb/ros-foxy-tf2-0.13.14/src/buffer_core.cpp
求大佬解决！

章节2.2中，在使用功能包组织python节点时，在代码和步骤都完全正确的前提下，每当使用colcon build指令后构建的包一直是Starting >>> ros2_cpp，并不是所命名的demo-python-pkg，无法构建出python功能包。

输入ros2 run demo_python_tf dynamic_tf_broadcaster后
Traceback (most recent call last):

在学习第六章第七章内容的时候，使用gazebo的时候，gazebo会崩溃，然后小车会消失，怎么再一次找回小车呢？

报错如图：8d3072e1-949a-492b-8137-12d3db17ef34-2025-08-21 15-50-43 的屏幕截图.png /home/user/图片/2025-08-21 15-50-43 的屏幕截图.png
尝试重装boost,但autoremove几乎会把一切环境都卸载。catkin_make -lboost_system也是报相同的错。在cmakelist里添加Boost::system的target_library也没有用。后面重装了ros，用的一键安装，其他都成功了但rosdep出错了，我后面手动安装了。之前因为anaconda的环境原因失败了几次，我卸载了anaconda3后虽然前面成功了，但后面这一步一直出错到现在都没解决，快疯了。大佬们，真心求教！

作为多年的机器人爱好者，我相信你一定也有和我们一样的痛苦：

“搭建一个完整的机器人仿真环境从来不是一件容易的事”
“别人发给我的仿真文件，第一次打开，永远是报错的......“

于是我们开发了rabo。它是一个新型的机器人开发平台，可以理解为浏览器版本的gazebo + 一键部署硬件能力。
打开浏览器，你就有了完整的机器人仿真环境和ROS2开发环境，还有各种共享的机器和场景资源可以直接上手，告别虚拟机，告别搭环境，告别安装失败，直接开工～

rabo历经几年时间的开发完成，到目前为止，它还只是在少数几所大学和研究所内应用。虽可挣得几分散碎银两，但作为一个还有那么一点技术理想的团队，我们还是无法摆脱一个渴望，那就是让更多像我们当初一样，在黑暗中苦苦摸索的机器人爱好者们，可以用上rabo，大家一起搞出更多有意思的东西...

所以我们准备面向轻量级开发者 免费 提供社区版rabo，包括上面提到的所有功能。社区版准备在8月底上线，感兴趣尝鲜的同学可以留言，我们提供测试链接～

这是一个示例场景：

Ubuntu22 ros2 humble
按照官方教程，从源码编译安装movei2后，

ros2 launch moveit2_tutorials demo.launch.py

运行信息看起来正常，rviz2能启动，只是rviz界面在屏幕外，也不知道怎么拉回屏幕中，有大佬遇到同样的问题吗，指点一下谢谢

我是ros2 humble 安装的moveit2
使用moveit_setup_assistant配置好的config文件夹，该做的设置都做了，demo.launch.py也能跑起来。
在我运行一个运动规划时报错：

我也怀疑过是未正确加载kinematics.yaml，于是我在demo.launch.py中加上print(moveit_config)，运行信息中打印出了moveit_config信息，其中包含
robot_description_kinematics={'robot_description_kinematics': {'manipulator': {'kinematics_solver': 'kdl_kinematics_plugin/KDLKinematicsPlugin', 'kinematics_solver_search_resolution': 0.005, 'kinematics_solver_timeout': 0.005}}},
各位大神，有没有遇到同样问题的，怎么解决
