Is it a bug on Guix side or upstream?  Because it seems that upstream
does not provide metadata information, at least, as usually expected.

Well, I have not yet inspected the PyPI package but it seems possible
that it is incorrectly packaged with the Setuptools standard.

Well, “guix import pypi httpie” works for me.

Hum, not necessary.  Well, I do not think that 'pip' uses all the
metadata from PyPI to install.  'pip' does dirty things and yes it
just works :-)  But this does not imply that PyPortfolioOpt is
correctly packaged as it is defined by PyPI standards.  I do not know
'poetry'.

Anyway. :-)  I am not finding the PEP defining the Python packaging
and the structure for a PyPI package.  Because it is not clear for me
if it is a bug on Guix side or upstream.

simon

`pip install PyPortfolioOpt`, `poetry add PyPortfolioOpt` runs for me. If
other python package installer can run, I suppose the upstream is correct.
Unless Guix is not as powerful as other python package installers, and
cannot work for certain type of PyPi packages. In this case, can this be
considered an improvement to be made?

This package PyPortfolioOpt is badly packaged upstream.  We cannot do
better than warn about the issue:
