Hello, To be installed, psycopg2 needs to know where PostgreSQL headers (.h files) and libraries (.a files) are situated. Header files are required by compiler while libraries are required by linker.
PostgreSQL provides special tool named "pg_config" that tells everyone where PostgreSQL is installed and where one should look for that files. This tool is part of postgres installation. Check you can run this program from your terminal. If you can't -- you need to find it and add it's folder to your PATH variable. "pip install psycopg2" runs "pg_config" to find your postgres installation.
