This tutorial assumes you have created the 'beginner_tutorials' package in the preceding tutorial on Creating a ROS Package.

i have already created the package but the problem is still there kindly suggest some another answer.

Then you most likely don't have your ROS_PACKAGE_PATH set up correctly, so your 'beginner_tutorials' package is not found by ROS. Have a look at this guide:

I have the same problem : my ROS_PACKAGE_PATH is correct : ~/ros_workspace:/opt/ros/electric/stacks: with beginner_tutorials correctly created within ~/ros_workspace

BUT : the command roscd is missing from /opt/ros/electric/ros/bin/, while most others commands seem to be there. I installed ros-electric-desktop and ros-electric-openni-kinect, on a Ubuntu 10.04 LTS regularly updated.

@Bruno Poterie you have a different issue. roscd is a bash function not a program. Please ask this in a separate question.
