× Encountered error while generating package metadata.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.


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.
