Cannot start Gazebo_ros

edit

I installed gazeboros using pre-built debians. after finishing, when i enter rosrun gazebo_ros gazebo, this message appears:

gzserver: symbol lookup error: /opt/ros/hydro/lib/libgazeborospathsplugin.so: undefined symbol: _ZN3ros7package10getPluginsERKSsS2RSt6vectorISsSaISsEE

gzclient: symbol lookup error: /opt/ros/hydro/lib/libgazeborospathsplugin.so: undefined symbol: _ZN3ros7package10getPluginsERKSsS2RSt6vectorISsSaISsEE

/opt/ros/hydro/lib/gazebo_ros/gazebo: 25: kill: invalid signal number or name: SIGINT

how can i fix it???
