I want to run the pi_face_tracker on my ROS, however, in the step of "rosdep install pi_vision", I always get error like: ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: pi_face_tracker_gui: Missing resource rosbridge

ROS path [0]=/opt/ros/groovy/share/ros ROS path [1]=/home/tishiba/catkin_ws/src/beginner_tutorials/rosbridge_suite ROS path [2]=/home/tishiba/catkin_ws/src/beginner_tutorials/pi_vision ROS path [3]=/home/tishiba/catkin_ws/src/beginner_tutorials/pi_vision ROS path [4]=/home/tishiba/catkin_ws/src/beginner_tutorials/pi_vision ROS path [5]=/home/tishiba/catkin_ws/src/beginner_tutorials/uvc_cam ROS path [6]=/home/tishiba/catkin_ws/src/beginner_tutorials ROS path [7]=/home/tishiba/catkin_ws/src ROS path [8]=/opt/ros/groovy/share ROS path [9]=/opt/ros/groovy/stacks anybody know how to solve the problem?

Hi @DavidXiong,

The pi_face_tracker_gui package (created by Scott Bell) requires the older Version 1 rosbridge package which can be found here. It looks like you have rosbridge_suite installed which I believe is the newer Version 2 rosbridge. So you can either install the Version 1 rosbridge or just comment out the <depend> line in the manifest.xml for the pi_face_tracker_gui assuming you can do without the GUI for now. (The rest of the pi_face_tracker package does not require the GUI.)

@Pi Robot, Thank U patrick, I do installed the newer Version 2 rosbridge,and after I comment out the <depend> line in the manifest.xml for the pi_face_tracker_gui, I can make the step "rosmake pi_vision" , however, in the next step--"roslaunch ros2opencv openni_node.launch", I got the error like:
