一、roslaunch husky_gazebo empty_world.launch报错

roslaunch husky_gazebo empty_world.launch  如果不能直接用tab补全，配置环境变量。

1、按tab不能直接补全。解决配置环境变量,根据自己的路径对照修改

source /home/mc/husky_ws/devel/setup.bash
source /opt/ros/noetic/setup.bash
export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:/home/mc/husky_ws/src/
export HUSKY_URDF_EXTRAS=$(rospack find husky_description)/urdf/empty.urdf

2、启动empty_world.launch后报错 resource not found: fath_pivot_mount_description

原因：缺少相关的包

解决:安装对应的包：sudo apt-get install ros-noetic-fath-pivot-mount-description

3、报错：resource not found: flir_camera_description

安装：sudo apt-get install ros-noetic-flir-camera-description

4、报错：resource not found: lms1xx

安装：sudo apt-get install ros-noetic-lms1xx

5、报错：resource not found: velodyne_description

安装：sudo apt-get install ros-noetic-velodyne-description
