Error when controlling actual xArm (real machine) with Moveit motion planner

[miko12306]

I ran roslaunch xarm6_moveit_config realMove_exec.launch robot_ip:=192.168.xx.xx and got the error (Red text in picture) shown in the picture.
Is there any solution to this problem?
The version of Ubuntu is 20.04 LTS and ROS is noetic.

@miko12306 , I would like to know did you build your ROS workspace and sourced it after cloning the repository, to me it looks like there might be following issue

1. Your bashrc does not have the location of your repository from where you are trying to run it .
2. Build your workspace and source it again .

Please let me know if this resolves your issue.
