    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
    <https://www.psycopg.org/docs/install.html>).

Ditto for an Alpine image. Also tried older versions of the package with no success. Same error message as @niloct.

[dvarrazzo]

Python 3.10 is not yet supported by the build pipelines so psycopg-binary is not available yet for Python 3.10

Closing this as there are dupes.

[beltiras]

I'm using python 3.8.10. I don't see the dupes, which I would gladly have attached myself on.

Never mind me. Alpine is not friendly to binaries.
