pyportfolioopt or PyPortfolioOpt inconsistency makes error in wheel installation

[AchmadFathoni]

Describe the bug When I try install wheel package using python -m build --wheel --no-isolation and python -m installer --destdir="$pkgdir" dist/*.whl I got

Traceback (most recent call last):

Expected behavior The key should be 'pyportfolioopt-1.5.1.dist-info/WHEEL' or wheel name should be PyPortfolioOpt-1.5.1.dist-info

Operating system, python version, PyPortfolioOpt version Archlinux, python 3.10, PyPortfolioOpt 1.5.1

Additional Context I got the PyPortfolioOpt 1.5.1 source from pypi

Thanks for raising this. I believe it's due to my build workflow, which uses poetry. I'm not sure it respects case sensitivity when it builds the wheels, which probably explains why on PyPi the package is lower case.

I'll have a look to see if there's a fix for this, perhaps in arguments provided to poetry build and poetry publish.

Lowering the case of the name in this line is working fix for me https://github.com/robertmartin8/PyPortfolioOpt/blob/102c593d54e979c1046ad5cf5d3e1a9c77dcd692/pyproject.toml#L2

Thanks for the fix! I'll double check that changing it to lower case doesn't lead to any problems elsewhere. If not, I will merge this in the next PR

[AchmadFathoni]

I think it is fixed, thank you.
