How can I fix this error from importing module pyautogui?

I run the python code from the root. Shows an error when I just imported the module:
ERROR : Traceback (most recent call last):

Django + Djangae + Nose / Fail wsgi

I'm currently trying to setting up django-nose in my project.
I also used Djangae (https://djangae.readthedocs.org/en/latest/) for app engine compatibility.
I add 'django_nose' in my INSTALLED_APPS
I set TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'
Launching "python manage.py test" is not raising any exceptions.
But when I want to launch the server with "python manage.py runserver", the server is running but when I try to call "localhost:8000" I get :
ERROR 2016-03-23 15:59:49,299 wsgi.py:263]

PyCharm Django test runner can't see django.sites (Runtime Error)

When I run manage.py test everything is working normally, but if run test with PyCharm Django Tests it gives me following error:

RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
Yes, I've enabled 'django.contrib.sites' in INSTALLED_APPS and SITE_ID is set.
Any ideas?

I created local virtualenv and install same requirements — tests work fine with it.
Thanks, everybody for comments.

CKAN error after enabling harvester module - 'module' object has no attribute 'ITranslation'

After enabling the harvester module for CKAN, I'm getting the following error in ckan_default.error.log (and the web application returns status 500 until I disable the harvest and ckan_harvester plugins from config file):

I found some similar errors but not for CKAN and 'ITranslation', any help appreciated.
Thanks

Fixed it! Just upgraded current 2.5.0a installation to latest DEV version (2.6.0a) and it worked without problems...
Thanks!
