Erro ao Instalar o psycopg2

Olá, realizei os procedimentos das aulas corretamente, mas estou com um erro no meu projeto na hora de instalar o psycopg2.

(venv) ranulfomascarineto@Ranulfos-MacBook-Air aplicacao % pip install psycopg2

      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.

Opa, bom dia.

Eu tive o mesmo problema e achei uma solução, porém foi uma solução no Linux, no windows não sei como seria:

sudo apt-get update
sudo apt-get install -y build-essential
sudo apt-get install -y python-dev
sudo apt-get install -y libpq-dev

pip3 install psycopg2

Em resumo, para o PyscoPG2 ser instalado é necessário q vc tenha o "python-dev" e o "libpq-dev"
