The problem about "?- rdf_triple(knowrob:forCommand,A,'make pancakes')."

Hi,

I am very interested in Knowrob project.I find it is powerful for the knowledge processing of robots. I install knowrob (groovy version) in the Ubuntu12, I install knowrob through rosbuild command. However,I meet a difficult problem.When I run the command in the terminal:

roslaunch opencyc opencyc.launch

Then I run the commands in another terminal:

roscd comp_ehow

rosrun rosprolog rosprolog comp_ehow

?- rdf_triple(knowrob:forCommand,A,'make pancakes').

But there are many warnings and errors appearing in the treminal:

WARNING: [Local Folder Repository] The specified file must be a directory
(/home/use/catkin_ws/src/stack/knowrob_addons/comp_ehow/plugins/edu.stanford.smi.protegex.owl) -- LocalFolderRepository.update()

Could you help me solve the problem?Thanks a lot! I’m looking forward to your reply.@moritz

Sincerely yours, Munu

Could you please format your question properly? Use the Preformatted Text button (the one with 101010 on it) for code and console copy-pastes.

And please don't indent every sentence with 4 spaces or more for regular text, as that triggers the code formatter.
