I have not managed to install PyQt6 in a few days to this error message:
ERROR: Could not find a version that satisfies the requirement PyQt6-Qt6>=6.3.0 (from pyqt6) (from versions: none)
It happens when I install like this:
python -m pip install --index-url https://www.riverbankcomputing.com/pypi/simple/ PyQt6
If I instead install without --index-url, it fails on installing the build depenencies with the following error message:
AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel'
PyQt6 itself seems to be properly located and downloaded from pip. However, it then automatically tries to also find PyQt6-Qt6 and that does not work. What am I missing?
Python 3.9.7, pip 22.1.2, setuptools 62.3.2.
