The issue here is that the two oldest releases of

lexid

have wheels with

pypy27

pyver tags. For example: https://pypi.org/project/lexid/2020.1003/#files Which has

<https://files.pythonhosted.org/packages/d0/29/c6ca27464a82787ffd9be6f19be6c2715cc660957a39ec689bc1654fd89d/lexid-2020.1003-py38.pypy27-none-any.whl>
