I'm currently struggling to install a python package in a virtual environment. The set-up is the following: I have an M1 mac and with it, I have the system python installations located in /usr/bin/python (v 2.7.18) and usr/bin/python3 (v 3.8.9). Since I don't really like messing with these, I have installed pyenv and pyenv-virtualenv over brew. I installed Python 3.10.1 and created a virtual environment, let's call it test. I also added the following lines to .zshrc
if command -v pyenv 1>/dev/null 2>&1; then
eval "$(pyenv init -)"
fi
alias brew='env PATH="${PATH//$(pyenv root)\/shims:/}" brew'
PATH=$(pyenv root)/shims:$PATH
(Most of this was done by following the explanations on the github page of pyenv).
I'm now trying to install some packages in test. numpy, scipy, etc worked perfectly but when I try to install PyQt5 with pip I get an error.

What exactly is going on here? Is this related to the m1 chip or the set-up of the virtual environment? How can I fix this?
On the suggestion of @pedro_bb7 I downgraded Python to 3.9.9 (since PyQt5 is not yet ready for Python 3.10.0) and also tried installing an older versions (5.14.1/2/, 5.15.0/1/2/3/4/5/6) of PyQt5 over the command
❯ pip install PyQt5==5.14.0

As you can see, still no luck...
