So I uninstalled it from the above user and re-installed it as root that user warning went away however now I am getting the below exception. Do I have to set the environment variables now?

django.core.exceptions.ImproperlyConfigured: Requested setting IMAGEKIT_CACHE_BACKEND, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I edited your Issue and comment to correctly show the output from the terminal to be easy to read. It's better to use Markdown when you want to show portions of code.

Now to the real issue.

1. You have user legacy. If virtual environment is in that user you should never use sudo pip or executing pip as root user. You totally messed up the permissions in the home folder of the legacy user. I'm suggesting you to fix ownership in all directories inside /home/legacy/ by executing sudo chown -R legacy.legacy /home/legacy/
2. In your second try you have successfully installed django-imagekit but you are not using it right. This is Django addon and can't work outside of Django environment. As the error says django.core.exceptions.ImproperlyConfigured it want's some settings to be set from Django, but Django is not configured yet.

This is not a problem with Imagekit but problem with your environment. I'm closing this issue.
