humble版本执行 ros2 launch fishbot_cartographer cartographer.launch.py 时出错

[vico1999]

source install/setup.bash
vico@wp:~/fishbot_ws/src$ ros2 launch fishbot_cartographer cartographer.launch.py
[INFO] [launch]: All log files can be found below /home/vico/.ros/log/2023-02-22-19-08-53-718889-wp-7239
[INFO] [launch]: Default logging verbosity is set to INFO
[ERROR] [launch]: Caught exception in launch (see debug for traceback): executable 'occupancy_grid_node' not found on the libexec directory '/home/vico/cartographer_ws/install/cartographer_ros/lib/cartographer_ros'

我的软件是22。04的ubuntu。装的是ros2 humble. 按照小鱼的文档操作后。在做上述launch时。提示找不到occupancy库，我按提示的路径去找，果然没有。 。我是源码安装的。怎么解决呢
