Error while migrating model?

Question

Django

It seems everything was fine, I'm trying to add a few models today and I get an error.
Tried googling, but couldn't find anything. What could be the problem? python 2.7.9 django 1.7.7

File "D:\OpenServer\domains\virtualenv\myenv\lib\site-packages\django\contrib\contenttypes\migrations\0002_remove_content_type_name.py", line 17, in <module>
    class Migration(migrations.Migration):
  File "D:\OpenServer\domains\virtualenv\myenv\lib\site-packages\django\contrib\contenttypes\migrations\0002_remove_content_type_name.py", line 34, in Migration
    migrations.RunPython.noop,
AttributeError: type object 'RunPython' has no attribute 'noop'

Answer 1

Judging by the documentation, .noop is only from 1.8

static RunPython.noop()¶
New in Django 1.8.
Pass the RunPython.noop method to code or reverse_code when you want the operation not to do anything in the given direction. This is especially useful in making the operation reversible.

Answer 2

I understood how it happened. after updating some scripts through the panel in pycharm, for some reason, django was updated to version 1.8, although I did not choose it for updating. Before that, I made a backup of all the files of the virtual environment, the project and the database. I tried to restore files from the backup of the virtual environment, the django version became the same as it was 1.7.7 - but the problem remained. What else needs to be fixed?
