problem installing via pip

Describe the bug

I'm not sure what the problem is here:

To Reproduce

Trying to install this python module on my openwrt based router

# uname -a Linux GL-MT3000 5.4.211 #0 SMP Thu Jun 20 15:15:09 2024 aarch64 GNU/Linux

Additional context Add any other context about the problem here.

pip3 and python3 installed via opkg -- updated pip3 to the latest version via pip upgrade.

Looks like you might have run out of ram.

Check the dmesg to see if the OOM killer got you

Yes! That was it.. I'm not sure how to get more ram. This is a very small router -- I will try to stop some unneeded services. I'm not sure why this is showing up now, I've installed lots of larger packages via pip before without issue. It has 512mb of ram. https://www.gl-inet.com/products/gl-mt3000/

You can install with export SKIP_CYTHON=1 to skip the cython acceleration. It will be much slower though

[3ricj]

That worked perfectly. Thank you.

export SKIP_CYTHON=1 fixed my problem. Thank you!
