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

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：

求解，一步步跟着教程来的，为什么会出现构建失败的情况

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：
[ERROR] [1755228331.551841031] [move_group_interface]: MoveGroupInterface::plan() failed or timeout reached
[ERROR] [1755228331.552188515] [moveit_ik_demo]: Plan (pose goal) FAILED
同时[WARN] [1755228291.666113659] [moveit_ros.robot_model_loader]: No kinematics plugins defined. Fill and load kinematics.yaml!
很奇怪，
demo.launch.py内容如下

from moveit_configs_utils import MoveItConfigsBuilder from moveit_configs_utils.launches import generate_demo_launch def generate_launch_description(): moveit_config = MoveItConfigsBuilder("zhijiao_robot", package_name="zhijiao_robot0802_moveit_config").to_moveit_configs() # print(moveit_config) return generate_demo_launch(moveit_config)

demo.launch.py运行信息：

This situation occurs when libraries containing plugins are directly linked against an executable (the one running right now generating this message). Please separate plugins out into their own library or just don't link against the library and use either class_loader::ClassLoader/MultiLibraryClassLoader to open.

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

想用ros和unity进行仿真，在github上找的项目运行不下去，放假回来电脑崩溃了要重新开始，有没有人可以帮帮我！！可以有偿咨询。
