Обсуждение: Error while trying to install in 3.11

I just install Python 3.11, and am trying to install psycopg2 with pip and am getting errors.
Seems to install just fine when I go back to 3.10, but 3.11 is giving me errors.

Seems to be the same error whether I'm trying to install psycopg2 or psycopg2-binary.

This is on Windows. Below is the copy/paste of the pip output for trying both psycopg2 and psycopg2-binary

Install has:
pip: 22.3
setuptools: 65.5.0
wheel: 0.37.1

Any help appreciated.

      pg_config is required to build psycopg2 from source.  Please add the directory

      If you prefer to avoid building psycopg2 from source, please install the PyPI
