rosmake and roscreate-pkg not responding

edit

Hi, I'm pretty new to ROS so please excuse me if I forget to mention stuff. I was working on a project today. I think it doesn't matter what it was about. At some point when I was working on a .cpp file I tried to rosmake it, as I have done before dozens of times. At this time, however, nothing happend. I waited for a couple of minutes without anything changing. After that couple of minutes I used ctrl+c to terminate rosmake. This is what was printed in the terminal:

Traceback (most recent call last):

  names = listdir(top)
KeyboardInterrupt

It somehow seems that it freezes for some reason.

I have no idea what any of this means. And I unsuccessfully googled this error. When I try to run roscreate-pkg or roswtf I get similar results. rosrun however seems to work.

Thanks for your help!

Cheers, Lukas

edit: The output is from roscreate-pkg!
