Can't find manage.py after installing graphite-web/carbon/whisper on RHEL 8 to set up graphite.db

[emboehm]

I used the following commands to install graphite, carbon and whisper on RHEL 8

yum install python3.11-mod_wsgi
pip3 install --no-binary=:all: https://github.com/graphite-project/carbon/tarball/master
pip3 install --no-binary=:all: https://github.com/graphite-project/graphite-web/tarball/master
pip3 install --no-binary=:all: https://github.com/graphite-project/whisper/tarball/master

I am unable to set up graphite.db. There is no manage.py anywhere under /opt/graphite/webapp or anywhere in the filesystem.

I can't find django-admin.py but I did find

/usr/local/bin/django-admin

but this command fails

cd /opt/graphite/webapp/graphite
PYTHONPATH=/opt/graphite/webapp:$PWD /usr/local/bin/django-admin migrate

which gives an error about USE_I18N

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Requested setting USE_I18N, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I also tried

PYTHONPATH=/opt/graphite/webapp:$PWD /usr/local/bin/django-admin migrate --settings=local_settings.py

which complains about local_settings.py

ModuleNotFoundError: No module named 'local_settings.py'; 'local_settings' is not a package

Is there something wrong with the method I used to install graphite-web, carbon and whisper?
What is the correct way to create graphite.db?
