importing PIL into a rosnode

Question

when I have the line

"from PIL import Image"

in a node, I get the following error when running my node via rosrun

"ImportError: No module named PIL"

of course, PIL is installed in

/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/PIL

but is not an ROS library. How can I change my manifest.xml to find PIL? If I understand correctly, rosrun clobbers my existing PYTHONPATH (when running python I can import PIL just fine).

Answer 1

I resolved it by explicitly putting PIL in my .bashrc's PYTHONPATH

oddly, however, python from the command line runs python 2.6.6, but rosrun on a python node somehow invokes python 2.6.1
