Answer 1

After hours of trial and error, I was finally able to solve this. My successful configuration is:

1. Open terminal with Rosetta 2 (https://dev.to/courier/tips-and-tricks-to-setup-your-apple-m1-for-development-547g)
2. Use non-homebrew python (mine was in /usr/bin/python3) to create virtual environment

/usr/bin/python3 -m venv env
source env/bin/activate

3. Upgrade pip

pip install --upgrade pip

4. Install PyQt5

pip install PyQt5

Answer 2

I needed PyQt5 as a dependency for a Python library and this worked for me. See original post here.

brew install pyqt5
echo 'export PATH="/opt/homebrew/opt/qt@5/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/opt/homebrew/opt/pyqt@5/5.15.4_1/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
