然后出现了这个错误

[gazebo-3] process has died [pid 49654, exit code 255, cmd /opt/ros/melodic/lib/gazebo_ros/gzserver -e ode /home/z/PX4_Firmware/Tools/sitl_gazebo/worlds/empty.world __name:=gazebo __log:=/home/z/.ros/log/27c686fc-5ffe-11ed-b47f-000c29811302/gazebo-3.log].
log file: /home/z/.ros/log/27c686fc-5ffe-11ed-b47f-000c29811302/gazebo-3*.log

但是gazebo能正常打开
