Hey guys, I'm struggling with getting the dependencies correct for a python package I'm building. Could anyone take a look? https://gist.github.com/Slabity/34f82cdb7cf149483042a8fa530b75fd

Building this results in the following:
ERROR: Could not find a version that satisfies the requirement pluggy<0.7,>=0.5 (from pytest==3.3.1) (from versions: none)
ERROR: No matching distribution found for pluggy<0.7,>=0.5 (from pytest==3.3.1)
