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.
If no files have been changed, it's a bit of mystery, but the only time I have run into this error in the past when a node script is really in the right place pointed to by the launch file is that the execute bit on the script is not set. To fix: "chmod 755 node.py". But I'm guessing you have already checked this. You could also try running "make clean" followed by "rosmake" in the package directory as well as "rospack profile".

Thanks for the response. Our file syncing tool had reset the permissions on source files to 744, so chmod-ing was the answer.
