Description

I am failing to install PyExFill with pip (pip install --user PyExfil) but it fails due to the following error:

➜  pip install --user PyExfil
Collecting PyExfil
  Using cached PyExfil-1.10.4.tar.gz (5.2 kB)
  Preparing metadata (setup.py) ... done
Requirement already satisfied: requests>=1.0.0 in /home/oma/.pyenv/versions/3.11.2/lib/python3.11/site-packages (from PyExfil) (2.28.2)

ERROR: Cannot install pyexfil==1.10.4 and pyexfil==1.3 because these package versions have conflicting dependencies.

The conflict is caused by:
    pyexfil 1.10.4 depends on zlib
    pyexfil 1.3 depends on zlib

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

The zlib library is a module from the standard library (link) and i have installed both packages (zlib1g zlib1g-dev) recommended by different stack overflow questions. So the requirement should be fulfilled.

Info about my system:

  • Kali on WSL (Windows subsystem for Linux)
VERSION_ID="2023.3"
VERSION="2023.3"
VERSION_CODENAME=kali-rolling
  • Python version: Python 3.11.2

Research direction

Start by reproducing the reported pip install --user PyExfil failure with Python 3.11, then inspect the package metadata generated from setup.py. Check how the releases declare zlib and compare that with Python's standard-library module and the reported pip resolver output. Done means installation no longer treats zlib as an unsatisfied package dependency.
