I'm trying to learn Django channels, so for the beginning, I simply installed and added "channels" to the Django project, INSTALLED_APPS in the settings.py, as showing below.
Installed channels with pip:
pip install channels
Installed versions:
channels 3.0.3
daphne 3.0.1
Django 2.2.13
settings.py > INSTALLED_APPS:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',
...
'django_ace',
'channels', # added this
]
I just installed one package and added one line to the settings.py so this shouldn't be an error, but when I try to run the server python .\source\manage.py runserver I got an error as showing below.
> python .\source\manage.py runserver --noreload

I did google and seems it's not version compatibility issue between django and channels, what's wrong with my project?
(added)
I tried pip install pypiwin32 seeing Error after adding Django channels to installed_apps in settings file - Stack Overflow, but it didn't solve anything, and stil the same error.

I am starting out in django-cms and I am trying to install cms from the official cms documentation. I created my virtual environment and installed Django and django-cms.
The next steps are to create a project with django-admin, and adding the django-cms in the installed apps. The project is going great till now. But, when I try to migrate my installed apps in the database I get the error "No module named 'packaging'". I don't understand what I am doing wrong. Another tutorial tells me to startproject using djangocms myproject
but it doesn't work (it's probably outdated as I couldn't find any variations anywhere else)
My settings.py:
INSTALLED_APPS = [
'djangocms_admin_style',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',
'cms',
'menus',
'treebeard',
]
SITE_ID = 1
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
}
}
LANGUAGE_CODE = 'en'
LANGUAGES = [
('en', 'English'),
]
After this, I run the
py manage.py makemigrations
But I get the error

ModuleNotFoundError: No module named 'packaging'
I am following the documentation from https://docs.django-cms.org/en/latest/how_to/install.html. I think it might have something to do with how the packages have been installed? But, I don't understand how to fix it.
Found the solution!
The packaging module was not installed by default, I upgraded my pip with py -m pip install --upgrade pip and installed the module with py -m pip install packaging and it works now.
I'm upgrading a Django site to 3.1.2 and noticed one backend app wasn't working, in the process of asking the community help in fixing this I found out the app wasn't a custom made code by a single coder for the site but a community project called django-import-export. Since it's up to date and supports django 3.1 i deleted the manual way it was setup as a folder and pip installed it. i then tried to do a makemigrations threw an error and after reading the setup docs assumed possibly you need to do collectstatic first, it also threw the same error

this somehow is related to installed_apps so I've included the entire list below
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
#site apps
'guides',
'pages',
#imported old dependencies
'blog',
'import_export',
'generic',
#imports
'comments_moderation',
'django_comments',
'sorl.thumbnail',
#additional django
'django.contrib.sites',
'django.contrib.humanize',
]
The traceback shows that the error occurs when loading GuideResource in your models.py.
The getting started docs for django-import-export suggest putting the resource in the admin.py, so I would try moving the GuideResource outside of models.py.

What can I do Now?.....
it is happening because of circular import in init.py file
follow the steps :
don't install this ...maybe u have done it ...
pip uninstall paypal
no need to delete migrations unistall it and reinstall it properly
pip install django-paypal
don't forget to add " - " in that because this is the reason for that issue ...
this worked for me !
try and give a upvote if works . Thank You in advance
You just need to install django-paypal.
pip install django-paypal

i am using pycharm as my IDE and in bower apps, it shows jquery-ui and fullcalendar as unresolved, even though I have installed them. Any help is appreciated.
It seems like bower isnt really installed check that by pip list.
If it is so did you do ./manage.py bower install ?
I think you should have the PROJECT_ROOT variable set somewhere in your settings.py file.
BOWER_COMPONENTS_ROOT = 'Project root/components/'
should be something like
BOWER_COMPONENTS_ROOT = os.path.join(PROJECT_ROOT, 'components')
In my case the variable in the latest Django install was BASE_DIR

I have read the thread: Django upgrading to 1.9 error "AppRegistryNotReady: Apps aren't loaded yet."
I have tried using
import django
django.setup()
at the top of my settings.py file with no luck.
I've made an assumption that the problem is with the third party apps.
My main question is, how to start checking for invalid third party apps, since commenting them out one by one does not remove the error. I've checked every app's that I've installed via pip documentation, and added the required lines
to the INSTALLED_APPS in settings.py. It seems that some packages, such as django-jquery, django-libsass, django-ordered-model have not been developed for some years, however, according to django==1.9 release date, those apps should have worked on django==1.9 (or maybe that is the mistake of my thinking?).
I am ready to post more information from my project if needed.
My settings.py fragment:
INSTALLED_APPS = (
'hvad',
'compressor',
'filebrowser',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'jquery',
'tinymce',
'apps.frontend.ad_akumuliatoriai',
'ordered_model',
'geoposition',
)
The output of "pip freeze":
Django==1.9
django-appconf==1.0.2
django-compressor==2.2
django-filebrowser-no-grappelli==3.7.4
django-geoposition==0.3.0

The traceback suggests you are importing a model in your settings.py:
from apps.frontend.ad_akumuliatoriai.models import Language
You shouldn't do this. Remove the import.
