One of my teamates can't compile our school project. The catkin_make command give this error :
ImportError: "from catkin_pkg.topological_order import topological_order" failed: No module named catkin_pkg.packages
Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.
We compared our PYTHONPATH and we have the same :
/opt/ros/groovy/lib/python2.7/dist-packages
We tried to reinstall ROS completely, but it doesn't work even after that.
Any suggestion to fix this?
