回答1:

Using pip :

pip install django-cors-headers

Using pipenv :

pipenv install django-cors-headers

I had the same problem after installed via pip. Then i downloaded source and manually installed the django-cors-headers after that the problem was gone.

Hope that helps.

From your traceback, it looks like you are not running the Django app in virtual environment. You could do two things:

1. Install django-corsheaders system wide so it's available to your app, with or without virtual environment

2. Or you activate the virtual environment and run the django app (since you have already confirmed that django-corsheaders is installed in virtual environment.)
