Error when trying BasicTurtleDemo

[jeffRowley321]

Hi,
I tried to run the BasicTurtleDemo from the tutorials but I get this error:

15:34:36 ERROR - core.states.execution_state: ExecutionState with name 'init_ros_node' and id 'INIT_ROS_NODE' had an internal error: ModuleNotFoundError: No module named 'rospkg'

I think this is issue is not related to RAFCON, but ROS or your ROS environment. Googeling for "ModuleNotFoundError: No module named 'rospkg'" has the following two links as first two search hits:
