Installation fails because zlib is not installed

[MagnusOffermanns]

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

➜  pip install --user PyExfil

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

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

Hey @MagnusOffermanns . Thanks for this.
Issue was supposed to be fixed on Python3 due to requirements3.txt. Python2 does need the zlib import but on 3 it's built in. Can you kindly confirm?

[MagnusOffermanns]

Unfortunately, I am still encountering the problem. I am installing PyExfill in a new environment.

I have updated my Python to:

• Python 3.11.9

Bump. I'm having this same issue trying to pip install the package.

Hey, there's still the same error with zlib ?? I'm trying to solve it but i can't find a solution. @ytisf is there a solution ??

[cookpoo78]

same for me

[TBAcikbas]

Any solutions yet ?

[ytisf]

Hey. This should be fixed in commit 6505180.
Would love to hear your feedback on how to mark this.

Hey, I saw the comment in Documentation.md, the problem is still persisting when using pip.

as for compiling from the source code I have met several problems.

• requirement3.txt > "pyobjc-framework-Quartz" causes a problem for debian based machines as it is for macOS (the requirements installation works if it's manually removed from the files)

• the setup.py is deprecated in 3.12:
  (testpyexfil) bato@bato-HP-ENVY-x360-2-in-1-Laptop-15-ew0xxx:~/testpyexfil/PyExfil$ python setup.py install
