Setting SECRET_KEY solved this for me.
$ export SECRET_KEY='secret key output'
One way to generate a secret key:
$ python3
>>> import random
>>> ''.join(random.SystemRandom().choice('abcdefghijklmnopqrstuvwxyz0123456789!##$%^&*(-_=+)') for i in range(50))
'some secret key output appears here'

I just generated the project and didn't do almost anything. The program works on my computer but not on my friend's. We have the same versions of python/django etc.
In production I divided settings to 2 parts prod_settings.py and local_settings.py. For server Gunicorn with Nginx. So after makemigrations command it returns
AttributeError: 'str' object has no attribute 'setdefault'

I think you kept the settings files name as prod_settings.py. I think by changing the file name to normal settings.py as Django assumes will fix the error.
If that too doesn't work, try running
python manage.py makemigrations
And then run
python manage.py migrate
Not just your settings.py file looks for settings. All of your app along with your project and even models.py, views.py, admin.py, test.py and urls.py of your project and most importantly Django in its backend looks for the settings of your project in the settings.py file. So you will need to change this from each and every place where Django looks for settings.py which is technically impossible. So the optimal solution is to change it back to settings.py
My problem is this: When I try to do the migrations, it gives me the following error:
python3 manage.py makemigrations

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
Thing is, I've never told django to use MySQL, in fact, the settings.py states that it has to use SQLite:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'gestlote.db'),
}
}
I've alreay tried to reinstall django, upgrade it, pip3 install pysqlite, but nothing seems to work.
So please, help me

It should have migrated after installation of memoize.

So far my project structure is:
I created a settings folder at project/project/settings and have three file base.py(The one I renamed and moved from project/project/name), production.py, staging.py, test.py which only includes one line from base import * and also an empty __init__.py.
For the account app it's under apps/account. And I already added urls.py. Also, I have added 'account' under INSTALLED_APPS in base.py.
Can someone please tell me how to fix this? Thanks a lot!
As you have changed the settings.py file to settings folder, you have to update the manage.py file to point out to the new settings module, In manage.py
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'example.settings')
# Here update the string 'example.settings' to the new settings module
# e.g os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings.test')
