[ros-users] import rospy "no module named msg"

[Brett Graham]

I'm trying to load rospy on a computer that does not have ros installed on it.

When I try:
import rospy

I get the following error:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

pysrc/<ipython console> in <module>()

pysrc/rospy/__init__.py in <module>()

ROS_HOSTNAME, ROS_NAMESPACE, ROS_PACKAGE_PATH, ROS_LOG_DIR

     50 import roslib.rosenv
     51 import roslib.roslogging

ImportError: No module named msg
---------------------------------------------------------------------------

I don't have the option to install ros on the computer (it's my phone
:) ). Is there a way to get around this, or am I misunderstanding how
to load rospy?

Thanks in advance for your help.
