I installed ros Indigo on a brand new raspbian wheezy follwing the tutorial from the wiki.

I get this

pi@RPiMower /opt/ros/indigo/bin $ sudo ./roscore
Traceback (most recent call last):
  File "./roscore", line 62, in <module>
    import roslaunch
ImportError: No module named roslaunch

but when i start python i can Import roslaunch without Problems.

pi@RPiMower /opt/ros/indigo/bin $ python
Python 2.7.3 (default, Mar 18 2014, 05:13:23)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import roslaunch

What's wrong?

Now i found

 export PYTHONPATH=$PYTHONPATH:/opt/ros/indigo/lib/python2.7/dist-packages

to solve that. Where would you put that line in?

But now i get

ROS master URI is not set

and will go on searching...

found out that export can do all that from the commandline - but is that really the way to do it? No config file or something like that?

The Problem is the use of sudo. try ist with without if you need the root rithgts then try dis

sudo su source /opt/ros/indigo/setup.bash ./roscore


source /opt/ros/indigo/setup.bash sudo -E ./roscore
