[gazebo-3]process has died && [gazebo_gui-4]process has died错误与解决办法

---

一、问题出现

运行 roslaunch mavros_posix_sitl.launch报错，出现[gazebo-3]process has died && [gazebo_gui-4]process has died错误。具体报错内容看着好像和gzclient以及gzserver有关，尝试了csdn的方法:

killall gzclient

killall gzserver

export SVGA_VGPU10=0

但是这些方法都不行。

二、解决办法

我查看了csdn的方法，有说查看gazebo版本，可能需要升级gazebo，于是当我运行gazebo --version时，发现有报错：gazebo：symbol lookup error，具体如下：

于是找到方法解决，方法如下：

sudo apt upgrade libignition-math2

之后再运行gazebo --version，发现没有报错了，能正常显示版本号。

三、问题解决

之后再运行:

roslaunch mavros_posix_sitl.launch

就没有[gazebo-3]process has died && [gazebo_gui-4]process has died错误问题了。

---

三、总结

出现[gazebo-3]process has died && [gazebo_gui-4]process has died错误，尝试执行以下指令。

sudo apt upgrade libignition-math2
