roscreate-qt-pkg error [closed]

edit

Ubuntu 12.04 ROS Fuerte

Hello team!

I will do a gui app with Qt and ROS and find this thread and follow the install instructions.

All works fine until run the script:

rosrun qt_create roscreate-qt-pkg my_package_foo

This show the next error:

~/workspace/dev$ rosrun qt_create roscreate-qt-pkg my_package_foo
Traceback (most recent call last):
  File "/opt/ros/fuerte/stacks/qt_ros/qt_create/scripts/roscreate-qt-pkg", line 3, in <module>
    from ros import qt_create
  File "/opt/ros/fuerte/lib/python2.7/dist-packages/ros/__init__.py", line 57, in __getattr__
    return __import__(name)
ImportError: No module named qt_create

What must I do to fix this error?
