At least for me with Python 3.9 and chess version 0.3.6.
I don't really understand how the way the parser is handling this at the moment works, although fanc seems to use the same approach successfully. All my google searching lead to a different way of handling this, like this, which works for me:
from .version import __version__
parser.add_argument('--version', action='version', version=__version__)
From what I've seen online it seems like from .version import __version__ only needs to be in __init__.py, but it didn't work until I added this into commands.py as well. I tried just adding that line at the top of commands.py and keeping the code the same, but that didn't help.
