Hi,

rospack find pr2_gazebo : gives no output.

I came across this problem when I tried to install the package pr2_gazebo.
Earlier everything was working properly.

I guess I did svn in the wrong directory. I did the following command in the
directory ~/ros/stacks/

svn co https://code.ros.org/svn/wg-ros-pkg


Here is the output of ls at folder ~/ros/stacks/

robot@robot-laptop:~/ros/stacks$ ls
camera_drivers  imu_drivers       pr2_ethercat_drivers  simulator_gazebo
common          joystick_drivers  pr2_gui               simulator_stage
common_msgs     laser_drivers     pr2_mechanism         slam_gmapping
diagnostics     laser_pipeline    pr2_power_drivers     sound_drivers
driver_common   navigation        pr2_robot             vision_opencv
geometry        physics_ode       robot_model           visualization
image_common    pr2_common        ros-pkg               visualization_common
image_pipeline  pr2_controllers   ros_tutorials         wg-ros-pkg

and output in the folder ~/ros/stacks/wg-ros-pkg/stacks

robot@robot-laptop:~/ros/stacks/wg-ros-pkg/stacks$ ls

How do I fix the problem. I am trying to work with Gazebo.

Thank you.
