Hello Dan: pylint is fully installed. Even with the latest pylint the issue still happens: $ cat li.py #!/usr/bin/env python """foobar""" import os print os.listdir(os.curdir) $ /usr/local/bin//pylint --version pylint 1.6.5, astroid 1.4.9 Python 2.7.6 (default, Oct 26 2016, 20:30:19) [GCC 4.8.4] $ /usr/local/bin/pylint --reports=n li.py ************* Module li E: 3, 0: Unable to import 'os' (import-error) What am I missing? Thank you! Bill On 01/30/2017 07:01 PM, Dan Stromberg wrote:

That's a pretty old pylint. Maybe update it?

Is pylint fully or partially installed?

What does "which pylint" say?

It could be you're mixing up your Python interpreter and runtimes. E.g. running a different 'python' than /usr/bin/python because it's earlier on your $PATH, or picking up some misconfigured /usr/local/bin/python that doesn't have its stdlib installed correctly. Try narrowing it down with only packages from the Ubuntu archive. Cheers, -Barry

Hello Jakub: To fix your issue just do a 'touch ~/pylintrc' Regards, Bill On 1/31/2017 2:44 AM, Jakub Wilk wrote:

Very odd. FWIW, I can't reproduce it in a clean Trusty environment. I get:

$ pylint --reports=n li.py No config file found, using default configuration

$ echo $? 0
