Is it possible to use psycopg2-binary
instead?

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 a subprocess, and is likely not a problem with pip.

I see this is documented here: https://pyrseas.readthedocs.io/en/latest/install.html#:~:text=If%20you%20install,before%20installing%20Pyrseas.
I'm going to go ahead and try to install them both locally using psycopg2-binary
and see if that works.
Okay, it does appear to install just fine without having PG installed locally when using psycopg2-binary
.
@jmafc any interest in a PR for this?
I'm afraid that since I haven't installed it recently, and apparently not many others have, this breakage is starting to occur. It's also a side-effect of having discontinued the Travis CI builds (after a long pause, it stopped working and I had trouble resetting it up). I've been considering using GH Actions, but haven't had time/other incentives.
@dvarrazzo can probably answer/explain this better than I can (and that of course, brings up the issue of moving forward to psycopg3).
To be clear, it works as long as you have Postgres installed locally (or at least libpq
), so it's not a big deal, but it does seem like if we could avoid that dependency, we should.
