I am new to ros and am still following the tutorials. I was following "Writing a Simple Publisher and Subscriber (Python)", but when I try to compile the code it shows "ImportError: No module named roslib".

I have ensured that PYTHONPATH contains $ROS_ROOT/core/roslib/src. But when I go to the file system, $ROS_ROOT/core is there, but roslib and src do not exist.

System Information: Using the fuerte Ubuntu VirtualBox Image.

N.B. ROS_ROOT is /opt/ros/fuerte/share/ros

I am new to ros and was wondering what exactly rosbuild and catkin are and what is the difference between the two.

Select the console that is running roscore and press Cntrl+c

I was following the tutorial WrittingServiceClient(Python). I have typed the code as it is. The project "makes" properly also, but when I try to rosrun the server or the client the following error shows:

from beginner_tutorials import * ImportError: No module named srv

Where am I going wrong? How to create the module srv?

N.B.: I have followed the tutorial "Creating a ROS msg and srv" and the srv file exists inside the beginner_tutorials/srv
