Tries to use python3.7 when python3.8 is installed

[rocketeeer]

I have python 3.8.5 installed on macOS Mojave, it looks like present is trying to use the python 3.7 interpreter even though it isn't present.

➜  python --version
Python 3.8.5
➜  pip3 install present

Very excited to use this btw! Totally understand if you are getting hugged to death from making the front page of hacker news https://news.ycombinator.com/item?id=24324099

I had a totally different understanding of the python_requires key in setuptools. https://packaging.python.org/guides/distributing-packages-using-setuptools/#python-requires

Looks like you need to set every Python version you support? I guess I can just remove it and add dataclasses are a requirement for older Pythons.

Oh I know why this is happening! python_requires works as expected but it was only added recently in 0.5.0. So when you install present using pip on earlier Pythons, it gets installed. Let me yank old versions from PyPI.

@kiote99 Thanks for reporting this. As for the original issue, I think python3.8 -m pip install present should solve it. Please reopen this if you still face the same issue.
