ROS报错：joint-state-publisher报错

[WARN] [1664518996.207303]: The 'use_gui' parameter was specified, which is deprecated.  We'll attempt to find and run the GUI, but if this fails you should install the 'joint_state_publisher_gui' package instead and run that.  This backwards compatibility option will be removed in Noetic.

问题出现原因：

找到想要打开的launch文件，里面用到了一个关节状态的一个发布者。

roslaunch xarm_description xarm7_rviz_display.launch

这条命令打开的是一个演示文件，常常用来在moveit配置助手配置完一个机械臂后，进行检查看配置的正确性。
