import select ImportError: No module named select

edit

Since yesterday I've been having a problem to use the next command:

$ rospack depends1 rospy

And any other command like this.

I receive the next output:

$ rospack depends1 rospy

I'm using Ubuntu 12.10 (Quantal), with ROS-HYDRO.

My rosdep version is:

$ rosdep --version

0.10.25

I've already tried to find some solution, but I couldn't. I've tried to 'autoremove' ros and clean install again, but nothing changed.

When I try to 'import select' using the python environment in terminal, everything is OK.

My PYTHONPATH is OK, as follows:

$ echo $PYTHONPATH

/home/usr/catkin_ws/devel/lib/python2.7/dist-packages:/opt/ros/hydro/lib/python2.7/dist-packages

Can anybody help me please?
