Hi, when I run "roslaunch gazebo_ros empty_world.launch", the error "Can't open /usr/share/gazebo//setup.sh" occurs at both the 'gzclient' and 'gzserver' . It's a weird path "/usr/share/gazebo//setup.sh", right? btw, I can't find the folder 'gazebo' neither.

Pls help, thx!

just paste the terminal prints:
