I have a problem with using the rqt_image_view package in ROS. Each time when I type rqt_image_view or rosrun rqt_image_view rqt_image_view in terminal, it will return:

Traceback (most recent call last): File "/opt/ros/kinetic/bin/rqt_image_view", line 16, in plugin_argument_provider=add_arguments)) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_gui/", line 59, in main return super(Main, self).main(argv, standalone=standalone, plugin_argument_provider=plugin_argument_provider, plugin_manager_settings_prefix=str(hash(os.environ['ROS_PACKAGE_PATH'])))
File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/", line 338, in main from python_qt_binding import QT_BINDING
ImportError: cannot import name QT_BINDING

In the /.bashrc file, I have sourced :

source /opt/ros/kinetic/setup.bash
source /home/kelu/Dropbox/GET_Lab/leap_ws/devel/setup.bash --extend
source /eda/gazebo/setup.bash --extend

They are the default path of ROS, my own working space, the robot simulator of our university. I must use all of them. I have already finished many projects with this environmental variable setting. However, when I want to use the package rqt_image_view today, it returns the above error info.

When I run echo $ROS_PACKAGE_PATH, I get the return:


And echo $PATH


However, when I only $ source /opt/ros/kinetic/setup.bash ,the rqt_image_view package runs!! It seems that, if I want to use rqt_image_view, then I can not source both /opt/ros/kinetic/setup.bash and /home/kelu/Dropbox/GET_Lab/leap_ws/devel/setup.bash at the same time.

Could someone tell me how to fix this problem? I have already search 5 hours in google and haven't find a solution.
