Hello,everyone! I'm a novice of ROS. I encountered a difficulty when using MoveIt!. The output is like this:

ros@ros-Lenovo-Product:~$ roslaunch moveitsetupassistant setup_assistant.launch ... logging to /home/ros/.ros/log/dacff944-5446-11e4-8c43-940c6d7adfff/roslaunch-ros-Lenovo-Product-8872.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

According to the implication, the command 'rosrun' is unknown when reading the file “/opt/ros/hydro/share/pr2_description/robots/pr2.urdf.xacro”.

I installed ros-hydro and MoveIt from source and added the following line to “~/.bashrc” :

source ~/roscatkinws/install_isolated/setup.bash

source ~/moveit/devel/setup.bash

It seemed that moveit’s setup have covered ros’s. What should I do in such circumstance?

Thank you for your attention!!!
