Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-9r2xzzk3/PyQt5/

As a workaround you can install the system package instead via "sudo apt-get install python3-pyqt5"
Then the pip install completes

i had different issues with debian buster and ubuntu 16.04
Fixed them in buster with:

apt install python3-pip python3-serial python3-pyqt5 --reinstall
pip3 install --upgrade pip
pip install tasmotizer
