[ros-users] [Discourse.ros.org] [OpenEmbedded] Python trouble

[Lars Larsen]

Hi 


I need a little assistance in hunting down an error in my  _meta-ros_ usage
roswtf keep reporting "mportError: No module named importlib"

This is clearly a missing python dependency somewhere, but where ??

I made my own packagegroup to pull in the ros components i want on target
