Installing psycopg2 into virtualenv when PostgreSQL is not installed on development system

Question

Is it possible to install psycopg2 into a virtualenv when PostgreSQL isn\'t installed on my development system—MacBook Pro with OS X 10.6?

When I run

Answer 1

All from the above doesn't work for me (OS Catalina 10.15.1)

There was a conflict with classical postgres and homebrew version. Please delete homebrew version by command

$ brew uninstall postgresql

and then install it from the official website:

$ sudo mkdir -p /etc/paths.d && echo /Applications/Postgres.app/Contents/Versions/latest/bin | sudo tee /etc/paths.d/postgresapp

It is actual for a simple psycopg2 install or django-heroku package.
