Postgres error when installing dependencies via pip

[martintoreilly]

Steps to reproduce

Hardware / OS: 15-inch Macbook Pro (2015) running macOS High Sierra (version 10.13.3 (17D102)

1. Clone citeas-api at commit f2b293b9cb47bb4c079528d8a95837b3db77be97
2. Create a virtual environment using virtualenv with the built-in macOS Python 2.7.10 (also replicated when setting up the virtual environment using a separately installed Python 3.6.4)
3. Activate the virtual environment
4. Try and install dependencies using pip install -r requirements.txt

Collecting psycopg2==2.6.1 (from -r requirements.txt (line 15))

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/kj/13ksgycx1lqcynzpcsl1btm00000gp/T/pip-install-jsrXgm/psycopg2/

Proposed solution

Update Postgres requirement in requirements.txt from psycopg2==2.6.1 to psycopg2==2.7. See issue on psycopg2 Githuib repo (via this Stackoverflow post).

Hi Martin. I noticed the same error a bit ago. The codebase is now updated to psycopg2 2.7.5 which resolved it on my end.
