The get_core_apps has been removed since django-oscar-2.0, as is described in the release notes:

Removed oscar.get_core_apps. Overriding apps is now done by replacing the Oscar app entry in the INSTALLED_APPS setting with that of the forked app.

You thus should remove the get_core_apps, and alter the INSTALLED_APPS instead. For example:

INSTALLED_APPS = [
    # Django apps
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'django.contrib.flatpages',

    # oscar apps
    'oscar',

    # your apps
    # ...
]

Now I am Getting this error...`ImportError: cannot import name 'OSCAR_MAIN_TEMPLATE_DIR' ` – msginfosys Aug 02 '19 at 10:05
@msginfosys: this is part of the release notes as well: *OSCAR_MAIN_TEMPLATE_DIR setting has been removed and existing templates updated with the full path. See #1378, #2250. Please update your templates accordingly.*. – Willem Van Onsem Aug 02 '19 at 10:08
I solve this issue after remove the 'OSCAR_MAIN_TEMPLATE_DIR' but now it's giving me another error `ModuleNotFoundError: No module named 'oscar.apps.promotions'`...as you mentioned in your reply i copy the same code and paste in my INSTALLED_APPS – msginfosys Aug 02 '19 at 10:11
@msginfosys: perhaps it is better to start with `'oscar'` and just look what apps are necessary? – Willem Van Onsem Aug 02 '19 at 10:13
I done it with `oscar` but i got this error...`LookupError: No installed app with label 'catalogue'. ` – msginfosys Aug 02 '19 at 10:16
@msginfosys: exactly, you thus will need to add that as well. By iteratively adding, you will eventually reach a minimum fixed point. – Willem Van Onsem Aug 02 '19 at 10:17
After adding required apps finally i got this error...`RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. ` – msginfosys Aug 02 '19 at 10:21
That's because your `django.contrib.sites.models'` should be in the `INSTALLED_APPS` as well. It is referenced by a model. – Willem Van Onsem Aug 02 '19 at 10:22
Now it's not importing anything from `from django.urls import path, include, patterns, url` and giving me this error `ImportError: cannot import name 'url'` – msginfosys Aug 02 '19 at 10:40
@msginfosys: `url` has been moved to `django.conf.urls`, so you should remove the `url` import (the last word), and use `from django.conf.urls import url`. It probably might help to read the release notes of the versions you upgraded... – Willem Van Onsem Aug 02 '19 at 10:41
Oh My God...It's installing now...all tables has been created in database...Thank You Willem for your Support... – msginfosys Aug 02 '19 at 10:48
Hi Willem, I have one more question, Can i implement this Module in my running website... – msginfosys Aug 02 '19 at 10:52
@msginfosys: what module? If you alter the settings, etc. you will need to restart the server. See https://docs.djangoproject.com/en/2.2/howto/deployment/ for more info. – Willem Van Onsem Aug 02 '19 at 10:53
I mean to say, I want to implement all the functionality of `oscar` in my running website,...and i have some errors when i am login my admin panel also...Getting this error when login my admin panel `DoesNotExist at /admin/login/` – msginfosys Aug 02 '19 at 10:58
@WillemVanOnsem I'm getting a similar error : Can you help ! – Earthling Jan 02 '23 at 03:31

Looks like 'get_core_apps' does not exists anymore.
