出现“/opt/ros/melodic/lib/gazebo_ros/gzserver -e ode /home/jize/turtlebot_ws/src/turtlebot_simulator/”

输入命令 roslaunch rotors_gazebo multi_mav_formation.launch 产生错误：

[gazebo-2] process has died [pid 9625, exit code 255, cmd /opt/ros/melodic/lib/gazebo_ros/gzserver -e ode /home/jize/turtlebot_ws/src/turtlebot_simulator/turtlebot_gazebo/worlds/playground.world

错误原因：

其实就是上次操作没有完全关掉gazebo，只是关掉了gui界面

所以使用命令：

killall gzserver && killall gzclient
