There are a couple things going on here. One bit is that you are running an unsupported Python version, it would seem. Python 3.14t? It would be helpful to point that out explicitly to bein with. :] Anyways, #19080 might address an aspect of this. You can try installing with pip install --extra-index-url https://pypi.chia.net/simple 'git+https://github.com/chia-network/chia-blockchain@less_than_4' miniupnpc. But... Given that's two versions ahead of what we support presently (3.9-3.12) I expect you will likely find more issues that we won't be helpful with until we get around to supporting those newer Python versions.

It would be helpful if you could list or OS and python version to be sure - please provide some more details

Fedora 41 with Python 3.14 free-threaded interpreter

check and make sure you install following presiquite packages:

gcc gcc-c++ gmp-devel libtool make autoconf automake openssl-devel libevent-devel boost-devel cmake

Maybe kinda related, install.sh failed on Arch because I have python 3.13.1. I made some changes to install.sh and saw it fail due to pyinstaller needing to be <3.13. I bumped pyinstaller to 6.11.1 in pyptoject.toml and updated with poetry lock and reran install.sh and it all worked fine. throws an error when I run chia

From pyinstaller release notes:

3.8-3.13. Note that Python 3.10.0 contains a bug making it unsupportable by PyInstaller. PyInstaller will also not work with beta releases of Python 3.14.

EDIT: I tried forcing a bunch of stuff in chia_policy.py to get things to work with 3.13, but nothing can seem to connect to my full-node: ClientConnectorError: Cannot connect to host localhost:8555 ssl:<ssl.SSLContext object at 0x7fae3b6034a0> [None]
But apart from it not being reachable, my full-node seems to be working fine, according to the logs.
I guess some work needs to be done to get this compatible.

This should get fixed in the upcoming release. It is in main but that is not pip installable.

#19080

pip install --extra-index-url https://pypi.chia.net/simple git+https://github.com/chia-network/chia-blockchain if someone wants. steps are being taken towards 3.13 support in #19123. there is no estimated timeline for completion of that. just need to roll through the various layers and resolve issues.
