I am trying to setup odoo on my ubuntu server. I tried to install the dependencies using pip3 install -r requirements.txt where requirements.txt has the package-name of all dependencies. The installation process stops with the following error 

Error: b'You need to install postgresql-server-dev-NN for building a server-side extension or libpq-dev for building a client-side application.\n'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-9oeydzud/psycopg2/

Which package given in the error should i install to resolve the error. Confused because installed libpq-dev on local computer.

    1. Try installing libpq from the latest pg repository (for example: "deb http://apt.postgresql.org/pub/repos/apt/ bionic-pgdg main" in apt sources for ubuntu 18.02). 2. If not working, try to install the "full" postgresql (including server) (I know, that's not a good option, but just to try) => What are the results? – Michael Hooreman Jun 11 '19 at 11:56
  • @MichaelHooreman So it's not postgresql-server-dev-NN. Ok . I was confused because this was the server! – p.ry Jun 11 '19 at 11:58

    @r.py Well, on my system, I have installed postgresql-11 and postgresql-11-client, from the repositories I've shown you, and pip install psycopg2 worked like a charm. Maybe please also consider using pg11 (I forgot to tell previously). – Michael Hooreman Jun 11 '19 at 12:01
