Fails to install on Windows (issue from docker-py)

[M-Davies]

Specs

• Docker Version: 4.10.1 (82475)
• Python Version: 3.10.5 (also tried on versions 3.10.0, 3.5.0, 3.6.8, 3.6.0 and 3.3.0)
• Exegol Version: latest (pulled from the repository)
• No WSL (it is installed but I am trying to make this work without it for now)

(let me know if you need any more information about my system)

Bug

Exegol fails to install on my Windows machine due to a dependency issue, both when installing via pip and when installing directly from this repository:

Looking at the log when trying to install packages directly, it's the docker~=5.0.3 package which is the cause since the updated version of the docker package uses the newer pypiwin32 package instead of the older deprecated pywin32 (thread for reference -> https://stackoverflow.com/questions/40981120/python-pip-cannot-find-pywin32-on-windows)

Failed Fixes

• Tried other python versions (I'm not sure which version of python3 is the one we're supposed to use on Windows)
• Cleared pip cache + reinstalled python
• Install packages directly

Could you possibly look into upgrading the docker version used by Exegol so this may work on Windows in the future?

Hello,

Indeed it's a known issue but we are already using the latest docker library, there is an issue opened docker/docker-py#2902
But the lib appears to not be maintained by docker anymore...

For now the (easiest) workaround is to downgrade to python 3.9 on Windows.

Depending on how things goes (lib maintained by the community in a near future for example) we will see if we'll have to fork or change to whole lib...

[M-Davies]

Ah ok, thanks for clarifying

[ShutdownRepo]

Re-opening this while there is no fix, so that we can keep it tracked

[M-Davies]

Looks like that issue got closed, they updated their pywin32 to 304 which is supported by Python 3.10 in docker/docker-py#3004

[Dramelac]

Yes indeed !
Now we just have to wait for them to release a new version of the lib. I'll close the ticket once the new version will be released and when the requirements.txt on exegol will be updated with the corresponding new version.
