You don't seem to have postgres installed, check how to install postgresql in your system, one of the way is brew install postgresql (if you use homebrew- recommended) or download the postgres app from postgresapp.com, pg_config should come with postgres and psycopg2 is trying to find it.

Run manually command including the path of pg_config program in PATH env variable, in my case:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin/

and then run

pip3 install psycopg2

EDIT:

Check directory of pg_config:

which pg_config
