'NoneType' object has no attribute 'strip'

[sumitjagdale]

I am trying to install moveit libraries from source on ros version kinetic. $rosdep install -y --from-paths . --ignore-src --rosdistro kinetic

Experienced an error as follow: ERROR: Rosdep experienced an error: 'NoneType' object has no attribute 'strip'

Thanks in advance!

I need the traceback if there is one. That is not enough information to easily find the problem.

This looks to be an issue in rospkg. maybe this should be ticketed on https://github.com/ros-infrastructure/rospkg

@sumitjagdale What platform are you experiencing this on?

@marcus9384 I assume yours is QNX based on the line number. Can you try to invoke /bin/uname manually.
