Issue

wheel_file_re fails to match version for packages with single digit versions. Example is markdown-captions package (filename markdown_captions-2-py3-none-any.whl). Results in the following error:

  • Installing markdown-captions (2): Failed

  AttributeError

  'NoneType' object has no attribute 'replace'

  at ~/.poetry/lib/poetry/installation/chooser.py:27 in __init__
       23│             raise InvalidWheelName("{} is not a valid wheel filename.".format(filename))
       24│ 
       25│         self.filename = filename
       26│         self.name = wheel_info.group("name").replace("_", "-")
    →  27│         self.version = wheel_info.group("ver").replace("_", "-")
       28│         self.build_tag = wheel_info.group("build")
       29│         self.pyversions = wheel_info.group("pyver").split(".")
       30│         self.abis = wheel_info.group("abi").split(".")
       31│         self.plats = wheel_info.group("plat").split(".")

I could recreate the issue with poetry add markdown-captions.

@python-poetry/triage
Seems like a severe enough bug.
