'pip install psycopg2-binary==2.8.3' fails with 'Error: pg_config executable not found.'

[Igneous01]

Trying to install the psycopg2-binary, and I am getting the same installation error about pg_config, even though it mentions in this error message that pg_config is not required with the binary?

OS: macOS Catalina 10.15.7

DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at pypa/pip#8333.

Error: pg_config executable not found.

pg_config is required to build psycopg2 from source.  Please add the directory
containing pg_config to the $PATH or specify the full executable path with the
option:

    python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.

If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.

For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

Binary packages for 2.8.3 are here: https://pypi.org/project/psycopg2-binary/2.8.3/#files

As far as I can see Python 3.8 is not available there: probably that release predates it.

Please install at least 2.8.4.
