resource not found: pr2_description

[LiukeyCC]

Hi, thank you for your code. However, when I try to follow the instruction and reimplement the whole project, the error happened. It seems that some files are missing. Could you please help? when I execute roslaunch ‘ur_robotiq_gazebo ur_robotiq_gazebo.launch’,

hint ‘resource not found: pr2_description’, when processing file: /home/ljh0929/myur_ws/src/ur_robotiq/ur_robotiq_description/urdf/ur_robotiq.urdf.xacro Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/kinetic/lib/xacro/xacro --inorder '/home/ljh0929/myur_ws/src/ur_robotiq/ur_robotiq_description/urdf/ur_robotiq.urdf.xacro'] returned with code [2].

Param xml is The traceback for the exception was written to the log file.
