This is a known issue. Use the binary version instead:
pip install psycopg2-binary
You dont have ‘pg_config’ which is part of
libpq-dev on Ubuntu. Install it with
sudo apt-get install libpq-dev and try abgain.
Before starting the binary installation, export PATH like below:
12 to your current PostgreSQL version.
