Cannot install psychopg on a mac m1

[pgmyrek]

I followed the readme until step 7 (poetry install) and then I get this error:

Installing psycopg2 (2.9.6): Failed

ChefBuildError

Backend subprocess exited when trying to invoke get_requires_for_build_wheel

      The license_file parameter is deprecated, use license_files instead.

      By 2023-Oct-30, you need to update your project and remove deprecated calls

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).

Note: This error originates from the build backend, and is likely not a problem with poetry but with psycopg2 (2.9.6) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "psycopg2 (==2.9.6)"'.

You may wanna install the package 'psycopg2-binary' and not 'psycopg2': poetry add psycopg2-binary Installation — Psycopg 2.9.6 documentation
