user error? or library?

[spencercap]

Hi- so happy this library exists, would love to get it working!

somehow i'm caught up at even the simplest sweep for devices on my network (LifxLAN().get_lights())

i'm on a mac running 14.3.1 w/ python v 3.12.4 i AM able to ping my devices' IPs from terminal (though 2 show up in my router's device list with 1 final digit different, 1 of them is ping-able)

here are the errors i'm seeing, any help would be rad! cheers

ah, solved (ish) downgraded to python v 3.6.15 and it works as expected.

didnt mess about further to find which version it breaks at

[deseipel]

same issue, I'm on Python 3.8.8.

Looks like this was fixed in this PR, as pointed out by this issue. I ran into this on Python 3.10.12, but I realized it may be because I installed using python3 -m pip install lifxlan. According to pypi.org, there hasn't been a release since 2021, so perhaps the fix didn't make it into pip yet.

@mclarkk - would it be possible to get an updated release so the pip method of installation pulls in the latest updates?

Is anyone running a modern version of Python? I stayed in an older version because everything works. Newer Python versions perform better so I would like to upgrade.

@HaberHash yes, I was able to get it working on Python 10. Instead of running python3 -m pip install lifxlan, clone the repo on your machine, cd into it, and install it with the setup.py script:

git clone https://github.com/mclarkk/lifxlan
cd lifxlan
python3 -m pip install ./

This got things working for me, and this bug has not been an issue.

@mclarkk - would it be possible to get an updated release so the pip method of installation pulls in the latest updates?

Done! Everyone with pip-installed lifxlan can get the fix now with pip install lifxlan --upgrade.

works! thanks @mclarkk 🙏
