== Installing catkin_pkg == {{{ sudo apt-get install python-catkin-pkg }}} The Debian package only contains the command line scripts and depends on another package named `python-catkin-pkg-modules` which contains the Python modules required for the scripts. This allows to install `python-catkin-pkg-modules` and `python3-catkin-pkg-modules` at the same time. === On non ubuntu platforms === Use [[ROS/Installation/EasyInstallConfig|pip]]: {{{ sudo pip install -U catkin_pkg }}} In case you experience error with the command above, you might want to run it without `-U` option. See [[http://answers.ros.org/question/65754/error-errno-89-function-not-implemented-while-source-installing-catkin_pkg/|this thread]].
