Hi all,
I was going through the ROS tutorials. After making the catkin workspace:
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ catkin_init_workspace
I try to run catkin_make as explained in tutorial:
$ cd ~/catkin_ws/
$ catkin_make
How ever I got an error msg :
ImportError: "from catkin_pkg.topological_order import topological_order" failed: No module named cmake Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.
python-catkin-pkg is installed and up-to-date. Also when I run $PYTHONPATH I get: bash: /opt/ros/groovy/lib/python2.7/dist-packages: Is a directory
I removed and reinstall ROS but didnt have any effect. I use ROS groovy and ubuntu 12.04.
How I fix this? Thanks

Did you install ROS using apt-get
?

Is this the tutorial you are doing? http://www.ros.org/wiki/groovy/Installation/Ubuntu. Have you initialized rosdep and source setup.bash?

Gustav, yes , I started from the installation and then gone to tutorials. I have initialized rosdep and sourced the setup.bash. Also I run rosdep update. but I get this: ERROR: unable to process source [https://github.com/ros/rosdistro/raw/master/releases/groovy.yaml]:
