Unable to import 'os' (import-error)
Hello:
I am trying to run a simple 2-line Python script through pylint on Ubuntu without success (see https://github.com/PyCQA/pylint/issues/1305).
Following are the details. Does anyone know what step I am missing?
Steps to reproduce
$ cat li.py #!/usr/bin/env python """foobar""" import os print os.listdir(os.curdir)
$ pylint --reports=n li.py ************* Module li F: 3, 0: Unable to import 'os' (import-error)
$ which python /usr/bin/python
$ python --version Python 2.7.6
$ ls /usr/lib/python2.7/os.py /usr/lib/python2.7/os.py
$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Ubuntu 14.04.5 LTS"
Current behavior
pylint reports an import error
Expected behavior
No errors should be reported by pylint
pylint --version output
$ pylint --version pylint 1.1.0, astroid 1.0.1, common 0.61.0 Python 2.7.6 (default, Oct 26 2016, 20:30:19) [GCC 4.8.4] @bdurant
Thank you,
Bill
That's a pretty old pylint. Maybe update it?
Is pylint fully or partially installed?
What does "which pylint" say?
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!

Hello All:
A new data point... I am seeing the issue only on Ubuntu 14.04.
It works fine on Redhat Enterprise Linux Server 6.6.
So it looks like pylint is broken on Ubuntu.
Is there a workaround/fix for Ubuntu 14.04?
Regards,
Bill

^^^^^^^^^^^^^^^^^^^^^^
"""foobar""" import os print os.listdir(os.curdir)
$ /usr/local/bin//pylint --version
^^^^^^^^^^^^^^^^^^^^^^^^^
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.

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
Hello Jakub:
To fix your issue just do a 'touch ~/pylintrc'

Bill
