Answer 1

I met the same problem. It's due to the version of ckeditor and the version of Django you use. My current django==1.9.8 which is not supported by django-ckeditor==5.6.1

My solution :

pip install django-ckeditor==5.3.0

If your Django version is between 1.8 and 1.10, this may work as well.

The Author has fixed this issue and updated in Github recently.

Answer 2

There is a version difference between the version of ckeditor you are using and the version used in the project. This same error was faced by me when I tried to run a pre-existing project.
