----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-_cf1z03a/psycopg2/

Ubuntu 18.04

How can I install it correctly?

Command used:

pip3 install uniq==2.1.22.* --no-cache-dir --index-url=https://engci-maven-master.cisco.com/artifactory/api/pypi/apic-em-pypi-group/simple

Solution

I think the best solutions is probably to upgrade to psycopg 2.7:

From https://stackoverflow.com/a/49292261:

The problem was fixed in #489 released in psycopg 2.7. We don't have plans to backport the fix to 2.6.

Well it says it's running python setup.py egg_info, so presumably from what is said below that's running python3 instead of python2.7. So perhaps check with ls -al $(which python). Then if it's going to python3, route the soft-link to python2.7 (temporarily) to run the script?
