It appears you are missing some prerequisite to build the package from source.

You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.

For further information please check the 'doc/src/install.rst' file (also at
https://www.psycopg.org/docs/install.html).

note: This error originates from a subprocess, and is likely not a problem with pip.
