I am facing this issue when trying to run psycopg2, any one with solution would be helpful, thanx!

Collecting psycopg2==2.8.6 (from -r requirements.txt (line 45))
  Using cached psycopg2-2.8.6.tar.gz (383 kB)
  Preparing metadata (setup.py) ... error

      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>).
      
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

This error appears when i try to run psycopg2 and I upgraded setuptools, still not solved.

    Have you installed python-dev?
    If you already have, try also installing libpq-dev

    sudo apt install libpq-dev python-dev

    If didn’t fix, try psycopg2-binary:

    pip3 install psycopg2-binary

    Try installing pip install psycopg2-binary it is a more stable package.
    or if you are on mac try brew install postgresql
