【解决[joint_state_publisher_gui-5] process has died】

出现问题：

在运行urdf文件（基于rviz）时，[joint_state_publisher_gui-5] process has died [pid 17913, exit code 1, cmd /opt/ros/melodic/lib/joint_state_publisher_gui/joint_state_publisher_gui __name:=joint_state_publisher_gui __log:=/home/robot/.ros/log/555593e6-69f1-11ec-9dee-701ce7f17e76/joint_state_publisher_gui-5.log].

解决：

当运行urdf文件，需要在luanch文件中用到控制关节运动的包joint_state_publisher_gui时，一定要去掉urdf的中文注释，建议改成英文。
