<div><div dir="ltr"><div>Someone has asked that I do a new release of importlib that includes a LICENSE file on PyPI: <a href="https://pypi.org/project/importlib/">https://pypi.org/project/importlib/</a>. Historically I have had the setup.py simply not include any Python code when built on versions of Python that include importlib in the stdlib itself: <a href="https://github.com/brettcannon/importlib/blob/master/setup.py">https://github.com/brettcannon/importlib/blob/master/setup.py</a> .<br></div>
<div><br></div>
<div>But now I would like to do a wheel. Is there some way I'm not thinking of to have a wheel that will leave out code or not install itself if a certain version of Python is used? Or will the user have to specify a proper Python requirement in their requirements.txt to get that kind of experience?<br></div>
