EDIT: management commands. Not comments. Auto correct..
I was using django 1.7.final.0 for a while, but am now trying to upgrade to 1.8 (..and eventually to the newest version).
When running manage.py help, the commands I see are only the base commands.
I've added a print statement, to see if INSTALLED_APPS works and it does.
import os
import sys
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings")
from config import settings
print(settings.INSTALLED_APPS) # prints apps like django-extensions that have commands.
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
There are no errors, but it simply doesn't list the other commands. If I try to run a command, like ./manage.py shell_plus it returns Unknown Command as can be seen below. Note the print statement, indicating that INSTALLED_APPS can be read.

Unknown command: 'shell_plus'
Type 'manage.py help' for usage.

The problem was in a dependencies. As this answer says MPTT was in need of an update.
I upgraded using the below, and now it works.
python -m pip install 'django-mptt==0.7'
