DistributionNotFound: argparse

[jakirkham]

Shouldn't happen (as it is included in Python 2.7, which I'm using), but does. If you aren't supporting anything before Python 2.7, maybe requiring argparse can be dropped altogether. Thoughts from other people, who have ran into this issue and tried to address it ( ros-infrastructure/bloom#194 ).
