Почему не могу привязать Postgres к Django (не устанавливается библиотека psycopg2)?

Я создаю проект на джанго по стандартной документации django.

На втором шаге, когда я подключаю вместо SQlite Postgres вылетает ошибка

Error loading psycopg2 module: No module named 'psycopg2'

Я пытаюсь установить модуль psycopg2, мне система выдаёт огромный текст ошибки:

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
).

Выполняю рекомендацию и делаю попытку установки библиотеки psycopg2-binary и появляется такая же ошибка.

Проблема тооооолько на mac os. На винде библиотека установилась без проблем и код работает без ошибок
