I am trying to run the bradtraversy simple todo list django code on my raspberry pi and have run into the following error. I have run into the following traceback:

I am fairly new to Django but thought I made all the correct adjustments to match my system specifics. I updated the settings file to match my allowed hosts and database setting and used the "python manage.py migrate" command to bring over migrations.
Any thoughts or help would be greatly appreciated. Thank you

I'm running my website on Django 3.2. I read in Django’s cache framework that MemcachedCache and python-memcached are deprecated. I installed pymemcache==3.5.0 on my staging server and changed to CACHE_URL=pymemcache://127.0.0.1:11211 in env.ini. But if I uninstall python-memcached with pip I receive an error message, that indicates that MemcachedCache is still used by my code, and it fails on import memcache.
My code uses the following imports:
from django.core.cache import cache
from django.core.cache.backends.base import DEFAULT_TIMEOUT
How do I replace MemcachedCache with PyMemcacheCache so that MemcachedCache will not be used in my code?
I'm using django-environ==0.8.1 and CACHES is defined in my settings:
CACHES = {
'default': env.cache()
}
env is defined as environ.Env().

I submitted an issue (possibly a bug) on https://github.com/joke2k/django-environ/issues/359
I don't know why, but the way I restarted my server during deploy doesn't refresh env.ini, and the server remembers the old settings. If I restart my server with sudo reboot, with the same settings, then CACHES is equal to {'default': {'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache', 'LOCATION': '127.0.0.1:11211'}} and the site works properly. And I confirmed that if I put dummy values in env.ini then the site doesn't work at all. But only if I restart my server with sudo reboot.
I am trying to run my Django server and I am facing the following issue. So, I am pretty new on Django, then Let me know if you need any additional information. This code is really complex to me and I am challenging myself to run multiples applications at the same time.

Very specific stuff. I'm running a Bitnami Django stack cloud VM on Amazon. On two different "regular" machines, I could install requests by running sudo pip install requests, but it seems that Bitname uses it's own specific structure, and something is going wrong when installing requests that way. It can also be related to issue #2028, but it was fixed long time ago.

Everything goes well till I come to the Chapter 3, section of creating the Hello World:

did you added <appname> to INSTALLED_APPS in settings.py
still errror then,
if you run django-admin.py startapp <appneam> from the project folder(\<mainfolder>\<projectfolder>)
the you want to try:
from <yourprojectname>.<yourappname>.views import hello
or you run django-admin.py startapp <appneam> from the folder contains manage.py(ie the \<mainfolder>\).
then do all the nessasary steps and then try:
from <yourappname>.views import hello
actually the djangobook is old and not updated frequently.
