问题


Looking for some help with an issue I am having with psycopg2 and Python3. I am trying to use the sql library from psycopg2 that is available in version 2.7.1. When trying to use

from psycopg2 import sql

I get the error message unresolved reference 'sql'

I am using Xubuntu Linux 16.04 LTS and when issuing the command

pip show psycopg2

in the terminal I get:

Name: psycopg2

Version: 2.7.1
Summary: psycopg2 - Python-PostgreSQL Database Adapter

Home-page: http://initd.org/psycopg/

Author: Federico Di Gregorio

Author-email: fog@initd.org

License: LGPL with exceptions or ZPL

Location: /home/bigdaddy/.local/lib/python3.5/site-packages

Requires:

So it appears to be installed in my system. Also in Pycharm when I go to File -> Settings -> Project Interpreter.. I see psycopg2 2.7.1 installed there as well. Any ideas of what is going on and why I am unable to use the psycopg2 sql functionality in my project? Everything appears to be installed to me it seems. Thanks for any help.

That is a common issue in PyCharm, follow those instructions: Unresolved reference issue in PyCharm and you will eliminate the problem!

For the case that the link does not work:

  1. Right click on your root project folder.
  2. In the tab that appears, find the Mark Directory as.
  3. In the expansion window that shows up, click the Sources root
