ubuntu20.04 ROS noetic 版本中rviz使用之前代码无法出现robot_state_publisher的滑动条的问题

1:首先判断你自己的系统是否安装

sudo apt-get install ros-noetic-joint-state-publisher-gui

确认安装好后，修改你的launch文件

修改之前：
<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher" />
修改之后：
<node name="joint_state_publisher_gui" pkg="joint_state_publisher_gui" type="joint_state_publisher_gui" />

2：如果你是出现下列错误

ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: Cannot 
locate node of type [state_publisher] in package [robot_state_publisher]. Make sure
file exists in package path and permission is set to executable (chmod +x)

修改之前：
<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" />
修改之后：
<node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher" />
