ModuleNotFoundError: No module named 'responsive_images'
You have to make sure you add the library to your INSTALLED_APPS list in settings.py. It's useful to keep in mind the library name as it's downloaded is usually different than it's name in pip. for Example this is installed with pip install django-responsive-images, but responsive_images is what you should include in your INSTALLED_APPS.

I would like to use https for my Django development server using django-sslserver.
I have installed it using
$ pip install django-sslserver
I have then added it to my settings.py INSTALLED APPS:
INSTALLED_APPS = [
...
'sslserver',
...
]
However, if I now try to start the sslserver like this:
python3 manage.py runssslerver 0.0.0.0:8080
I get the following error:

ModuleNotFoundError: No module named 'sslserver'
Any idea how to fix this?
If you are using native python in linux, the pip and pip3 is different. You can try pip3 install django-sslserver.
I recommend to use virtual environment in web service development of python, e.g. pipenv.
I'm tryin to deploy to Heroku and before this error I was getting:
ModuleNotFoundError: No module named 'django-tables2'
Then I installed django-heroku via pip install django-heroku, followed the instructions on how to set it up.
I disabled the collect static for heroku pushed my master branch and everything is fine, but once I do:
heroku run python manage.py migrate
I get the:
ModuleNotFoundError: No module named 'django_heroku'
the complete traceback is this:

ModuleNotFoundError: No module named 'django_heroku'
I have in my settings at the top:
import os
import django_heroku
and in the very bottom:
django_heroku.settings(locals())
in my requirements.txt I have django-heroku
The master branch is updated and I just can find how to fix this.
The problem was that it was not added to the module, it was needed to be added to the virtual env and then do the pip freeze, with that it was solved.
I have an issue with migration in Django using python3 manage.py migrate it shows me about memoize
I have installed django-memoize and included it on my settings.py but it still shows the error.

It should have migrated after installation of memoize.
Thank you for all the support I need to install some dependencies and re-install my python then after that I created a virtual environment and install dependencies.
I'm writing project using docker and django (2.1).
I've installed module 'django-widget-tweaks' inside a container and added 'widget_tweaks' to INSTALLED_APPS. When I start project using docker-compose up everything works well, but when I want to run something like docker-compose run <container name> python manage.py test in another terminal an error occurs.

But when I directly run the same command python manage.py test inside a docker container, it works. widget-tweaks has been installed both on container and on my machine. Could you advice something to solve the problem?
Thanks in advance!
My colleague started a django project on Ubuntu. I want to run the same project on OS X Yosemite. We both use python3.4 and following packages:
Django (1.8.2)
Pillow (2.8.1)
pip (7.0.3)
setuptools (17.0)
wheel (0.24.0)
And we both run project in virtual env.
When I cloned project, I used
python manage.py syncdb
And I got following results:

I have no idea why this happens and used several methods described in this site and other sites.
What happened and why?
This should have thrown an error on your Ubuntu install as well.
You need to change line 3 of projectName/main/admin.py to:
from .models import ContactLink, ContactPost, Personnel, \
WorkCategory, Service, Skill, Work, Customer
Notice the added dot . in the from .models part. The import should be relative (assuming all of these models exist in the same main app).
