Installation problems on MacOS

[jasonkaplan79]

I am trying to install this on my Mac. Here are my constraints:

• Hardware: Macbook Pro, Apple M2 Max running MacOS Sonoma (CPU, no GPU)
• I do not want to use Docker or any Virtual Machines

For the Frontend:

• How do I set NEXT_PUBLIC_API_SECRET_KEY and NEXT_PUBLIC_BACKEND_URL?
• Can I disable Recaptcha, or am I required to fill out NEXT_PUBLIC_RECAPTCHA_SITE_KEY and RECAPTCHA_SECRET_KEY

For the backend:
These are the steps I followed (which failed on my Macbook Pro, Apple M2 Max running MacOS Sonoma. I do not want to use Docker or any Virtual Machines):

$ cd backend
$ pip install -r requirements.txt

  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>).
