Unable to install PyQt6

[Ben Phillips]

Hi Team,

I am unable to install PyQt6 via pip:

    ERROR: Command errored out with exit status 1:
     command: /home/bob/app/venv/bin/python
/home/bob/app/venv/lib/python3.6/site-packages/pip/_vendor/pep517/_in_process.py
prepare_metadata_for_build_wheel /tmp/tmpxk7rx2bc
         cwd:

    Complete output (37 lines):
    Querying qmake about your Qt installation...
    /usr/bin/qmake -query
    Traceback (most recent call last):

line 126, in prepare_metadata_for_build_wheel
        hook = backend.prepare_metadata_for_build_wheel
    AttributeError: module 'sipbuild.api' has no attribute
'prepare_metadata_for_build_wheel'

Is this a known issue?

Regards,
Ben
