Re: django 2.0 tutorial :: exception:: application labels are not unique.

just a note on your note: I created a few more new project/app using PyCharm create facility and I found the app registered in the INSTALLED_APPS settings. I do not know if it is Django or PyCharm that introduce this setting. In the first case the Django tutorial documentation should be amended. In any case from now I follow the protocol of inspecting the INSTALLED_APPS settings after the creation of a new project/app.

Just to note: Django doesn't change the settings.py file, it only references it so it knows what configurations to load.

thanks for pointing out about the typo. However this was not the cause of the exception. Look to my previous answer.

As new to Django I am learning following the tutorial carefully. When I reached the point of making the migration for the polls app I executed (from the PyCharm terminal) the command:

(venv) C:\Users\Paolo\PycharmProjects\mysite>python manage.py makemigration polls

and then I obtained the following exception messages 

Traceback (most recent call last):
  File "manage.py", line 15, in <module>
    execute_from_command_line(sys.argv)
  File "C:\Users\Paolo\PycharmProjects\mysite\venv\lib\site-packages\django\core\management\__ini

    apps.populate(settings.INSTALLED_APPS)

    "duplicates: %s" % app_config.label)
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: polls

(venv) C:\Users\Paolo\PycharmProjects\mysite>

I reviewed carefully the code and restarted the tutorial several times , all the times having the same problem.

ANY SUGGESTION?? thanks
