Same - get this error, and cannot get eth-brownie installed on a Macbook Air 2020 with M1 chip no matter what method I try

1. pipx install eth-brownie
2. python -m venv venv => source venv/bin/activate => pip3 install eth-brownie
3. Git cloning the eth-brownie repo and running python3 setup.py install

@nilsbunger Python 3.9 works for me and yes I had the same issue where my system really wanted to use 3.10.0 as well. Using pyenv to manage the version didn’t work either. I had to uninstall 3.10.0 and do a fresh 3.9.5 install.

Thanks for the response!
