Django Crispy Forms

I am fairly new to Django and I have installed and am trying to use crispy forms in my web app.I have added crispy_forms to my installed apps with a comma after it. When I run the server I get this error:

Watching for file changes with StatReloader
Performing system checks...

Exception in thread Thread-3:
Traceback (most recent call last):
  File "c:\users\amart\django\django\template\utils.py", line 66, in __getitem__
    return self._engines[alias]
KeyError: 'django'

During handling of the above exception, another exception occurred:

I don't know what is wrong with my code. I have found some other users who have issues using crispy forms but are getting a different error. They were also unable to import crispy forms from the python shell but that is working for me. Even if I only add crispy forms to my installed apps without trying to apply it in my templates, I still get an error. Please let me know what I'm doing wrong. Thanks in advance.

Your version of django-crispy-forms is outdated, this has been fixed. Update it by running:

pip install django-crispy-forms -U

-U makes pip upgrade your current installation to the newest. You can find more about it by running pip install -h

The problem has been solved. I uninstalled the django version I had and used:

pip install Django==2.1.7

Thank you @YugandharChaudhari for helping me realize to change versions.
