Cannot locate python node
When executing my launch file, I get the error
ERROR: cannot launch node of type [package/node.py]: Cannot locate node of type [node.py] in package [robot]
for every node in the launch file. This script was working about 8 hours ago, and no files have been changed. Tried re-running rosmake.
using roslib.packages.findnode returns nothing for any node/package pair in the project.
