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

Actually the problem has been resolved now.

I was trying to run the talker.py code like you would normally run python codes. I realized later that you have to call make for it to run.

In fuerte, the roslib packages are installed to:

/opt/ros/fuerte/lib/python2.7/dist-packages/roslib

You should not have to change the PYTHONPATH manually yourself. Just sourcing /opt/ros/fuerte/setup.bash should set up everything just fine. PYTHONPATH should be something like:

/opt/ros/fuerte/lib/python2.7/dist-packages

To help you more, you need to provide more details such as what tutorial you are following and which step exactly fails.
