These don't work well with Guix for a number of reasons - but in my previous attempts to use them I found that Guix's use of PYTHONPATH meant that virtualenvs where never isolated from packages installed by Guix. Guix offers pretty much everything that virtualenvs offers, but it does things a little differently - you'll need to look at environments, profiles, manifests, and use of a guix.scm to recreate (IMHO) a better experience in the end. When I started using Guix I went to some lengths to harmonize virtualenvs and Guix - and others have made more substantial efforts than I did - but you end up creating as many problems as you fix: https://lists.gnu.org/archive/html/help-guix/2020-11/msg00237.html If you search the mail archive a couple of other people have asked similar questions to do with poetry, pyenv, pip, etc - they're all interesting reading and easy to grep with those keywords: https://lists.gnu.org/archive/html/help-guix/ The advice I was given at the time was don't mix package managers, and in hindsight I'm glad repackaged what I needed under Guix. I've packaged quite a few python libraries now, and most are pretty trivial to do - if they are in PyPi you can just use this: guix import pypi <package_name> If you need a later version than Guix provides (eg pandas), my advice is to use the ability to "inherit" the current definition in Guix and tweak the version. For Pandas I did this for a more recent version I needed and all I had to do was disable 2 unit tests (which failed for a non-Guix reason). Apologies - not exactly the answer you want (I have a stab at that below), but it's worth considering moving to Guix packaging exclusively to keep your life simple. > File > "/home/sl/.cache/pypoetry/virtualenvs/poetry-test-vOWX4_Vr-py3.8/lib/python3.8/site-packages/pandas/core/window/ewm.py", > line 9, in <module> > import pandas._libs.window.aggregations as window_aggregations > ImportError: libstdc++.so.6: cannot open shared object file: No such > file or directory If it's only missing a reference to the underlying C++ library you could install this library using Guix, or if you're using a foreign distro point to the non-Guix version under /usr/lib which, at a guess, Poetry may have picked up - but this is going to cause you more trouble down the line than repackaging in Guix in my experience.
