Dear all,

IN order to finish the tutorials of PR2 open a door, I do it like this.
http://www.ros.org/wiki/pr2_simulator/Tutorials/PR2OpenDoor

But when I finished the setp of installation,and change the environment
variable.

Something goes wrong.

yubin at yubin-laptop:~$ echo "source /opt/ros/cturtle/setup.sh" >> ~/.bashrc
yubin at yubin-laptop:~$ . ~/.bashrc
yubin at yubin-laptop:~$ roscd ros
yubin at yubin-laptop:/opt/ros/cturtle/ros$ roscore
Traceback (most recent call last):
  File "/opt/ros/cturtle/ros/bin/roscore", line 34, in <module>
    from ros import roslaunch
  File "/opt/ros/boxturtle/ros/core/roslib/src/ros/__init__.py", line 63, in

    return __import__(name)

    import roslaunch.loader

    from roslib.names import make_global_ns, ns_join, PRIV_NAME,
