Roslaunch is not working

[w4448756]

I finished building g2o and compiling the package, and then I downloaded the real-data example and run with "roslaunch camera_lidar_calibrator run_rosbag_velo.launch", but got the following error

I have tried to execute "source devel/setup.bash" and the result is still the same.
A screenshot of my compilation process is attached below

Please help me.
Thanks a million.
