Why does an error occur when migrating a database to Django 1.11.2 after cloning from Github?

Question

Django

Hi all!
Tell me, please, what could be the problem. The situation is this: there is a project in a private GitHub repository on Django 1.11.2 (not empty, in active development). I do git cloneit for him (upload from scratch), open it in PyCharm and enter in the console python manage.py migrate.

PostgreSQL 9.6.x is installed on the computer (Win8.1 x64), the user/table is created, settings.pyeverything is written in the project ( ), the test connection in the PyCharm settings is success.

I see this error:

$ python manage.py migrate

Traceback (most recent call last):
  File "...\Programs\Python\Python36-32\lib\site-packages\django\db\backends\utils.py", line 65, in execute
    return self.cursor.execute(sql, params)

                                                             ^
The above exception was the direct cause of the following exception:

It's also not clear why the initial DB initialization is not done (where the auth/sessions/etc tables are created)? How do you generally organize work with git for a Django project? What to ignore, and what to leave on the contrary?
I would appreciate any help...

There is a bug in the migrations somewhere. It is impossible to answer the question from the voiced initial data. You can only see the whole code and base, using the showmigrations, migrate --fake-initial, migrate, migrate --fake commands to try to solve the situation.
