机器人 —— ros报错： CMake Error at /opt/ros/jazzy/share/ament_cmake_core/cmake/core/ament_package_xml.cmake:95 (message): execute_process(/home/devil/.local/bin/python3.13

报错信息：

ModuleNotFoundError: No module named 'catkin_pkg'
CMake Error at /opt/ros/jazzy/share/ament_cmake_core/cmake/core/ament_package_xml.cmake:95 (message):
execute_process(/home/devil/.local/bin/python3.13

原因：

colcon 编译时指定的Python路径不对，使用colcon编译ros的第三方package时指定Python路径即可。

colcon build --packages-select carlike_robot_description   --cmake-args    -DPython3_EXECUTABLE=/usr/bin/python3

/usr/bin/python3 是Linux系统默认的，安装ros时自动识别的，因此这里使用该路径。

file:///home/devil/Pictures/%E6%88%AA%E5%9B%BE/%E6%88%AA%E5%9B%BE%202026-08-14%2019-39-04.png

检查package是否编译成功：

file:///home/devil/Pictures/%E6%88%AA%E5%9B%BE/%E6%88%AA%E5%9B%BE%202026-08-14%2019-44-07.png

source install/setup.bash 
ros2 pkg prefix carlike_robot_description

具体报错：
