      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 think psycopg2-binary package has been pre-built assuming that it would run on a Linux system which uses the glibc implementation as the standard C library. Termux runs on Android, which does not use glibc. So I think what is happening is that pip understands that and falls back to building psycopg from source, in which case the build dependencies should be installed before.

Try installing the build dependencies:

apt-get install libpq-dev gcc python3-dev musl-dev

See https://github.com/psycopg/psycopg2/issues/684

A web search for the same problem shows that this is also the case for other Linux systems that don't use glibc, like Alpine Linux.

This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: libllvm E: Unable to locate package libpq-dev E: Package 'gcc' has no installation candidate E: Unable to locate package python3-dev E: Unable to locate package musl-dev – Kim jon stack Mar 08 '22 at 09:21

For those who might care, on MAC Os I have successfully installed `psycopg2-binary` package, after installing the mentioned packages `brew install libpq-dev gcc python-yq` – monti Jul 18 '22 at 19:43
