PyQt6 Installation failed on building dependencies

Question

I am trying to install PyQt6 with pip. But it could not succeed.I am using python 3.9.0 32 bit in Windows 8.1.

I tried PyQt5 installation ,it works fine. I think there is something error with building dependencies and some metadata generation process. Is there any unofficial wheel for PyQt6? Can anyone help me out?

Here is the Error:
