Created on 27 Jul 2018 · 6Comments · Source: geerlingguy/ansible-role-postgresql

pip list shows psycopg2 (2.7.5)
yum shows this Package python-psycopg2-2.7.5-1.rhel7.x86_64 already installed and latest version
2a: python --version: Python 2.7.5
Ansible yml has this:

  roles:

      postgresql_python_library: python-psycopg2
      postgresql_bin_path: /usr/pgsql-9.6/bin
      postgresql_daemon: postgresql-9.6.service

Error thrown is this:

I already had python3-psycopg2 installed but it still failed with;
postgresql_python_library: python3-psycopg2

So i added the following to my playbook;
ansible_python_interpreter: /usr/bin/python3

Seems like by default it just used /usr/bin/python

On debian 10;
/usr/bin/python --version
Python 2.7.16

try with pip install -U --no-cache-dir --force psycopg2

This bug is a little annoying to figure out as no_log is being used in the cases where it crops up e.g. creating users, obscuring the real problem.

I personally fixed it by using package to install python3-psycopg2 before the Postgres role is imported.

Old thread (but open) same issue here on Ubuntu. removing no_log gave me the error message of missing package. After manual install psycopg2 the task for users is working. An extra step to install required python package should resolve the issue.
