Can not install psycopg2 on Mac 12.3, I keep getting this error

Ive recently bought a MacBook Pro and was setting it up for some python and Django programming but I ended up having problems installing psycopg2, I've tried several things already and none of those worked for me, here left the error,

Collecting psycopg2
  Using cached psycopg2-2.9.3.tar.gz (380 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

      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

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

It shows it is not a problem with pip but with setup.py but can not find anything,

any help would be welcomed

Thanks

As Alex mentioned, it is PostGreSQL being not installed on your system that throws up the error Install PostGreSQL and it will all work fine Try this

❯ brew install postgresql
# If you open a new terminal tab you will see that pg_config is available
❯ export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include"
❯ export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib -L${HOME}/.pyenv/versions/3.8.10/lib"
❯ python -V
Python 3.9.13
❯ pip install psycopg2-binary==2.8.6```

Late, but I just had this problem and nothing I was finding was fixing it. I was trying to install the requirements.txt for an ongoing project on a new Mac. Eventually I remembered it's a postgresql package and I hadn't installed postgresql yet. As soon as I installed postgresql and tried installing psycopg2 again, it worked fine with no errors.
