Я сделал wget bootstrap .pypa.io / ez_setup.py --no-check-certificate sudo python ez_setup.py sudo -H pip install psycopg2 и получил следующие ошибки. 

sudo -H pip install psycopg2

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Пробовал: 


 - brew reinstall openssl 
 - pip install psycopg2-binary instead of pip install psycopg2.

И работает.
