解决打开gazebo黑屏,“[gazebo-2] process has died [pid 9625, exit code 255, cmd /opt/ros/melodic/lib/gazebo“

输入命令 roslaunch turtlebot_gazebo turtlebot_world.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

解决方法

退出gazebo

killall gzserver

再重新打开gazebo即可
