本文详细介绍了在ROS开发过程中遇到的三个常见问题的解决方案：CMake错误、节点定义错误和模块未找到错误，并提供了相应的解决方法。通过执行特定的命令，读者可以轻松解决这些问题，从而继续进行ROS项目的开发。

1.CMake Error at CMakeLists.txt:28 (rosidl_generate_interfaces): Unknown CMake command “rosidl_generate_interfaces”.

解决方案：CmakeLists.txt中添加

find_package(builtin_interfaces REQUIRED)
find_package(rosidl_default_generators REQUIRED)

2. ndt_mapping_nodes: No definition of [osrf_testing_tools_cpp] for OS [debian]

解决方案：

ubuntu20.04版本运行：

rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y --os=ubuntu:focal

3. ModuleNotFoundError: No module named ‘transforms3d’

解决方案：

 pip3 install transforms3d

4. [cartographer_node-1] Warning: TF_OLD_DATA ignoring data from the past for frame base_link at time 55.566670 according to authority Authority undetectable

解决方案：将launch文件中use_sim_time参数值改成true

def generate_launch_description():
    use_sim_time = LaunchConfiguration('use_sim_time', default='true')
    cartographer_prefix = get_package_share_directory('cartographer_ros')
