image I try to use python 3.9 3.8 3.6 but not working. All the time working this bug ImportError: cannot import name 'six' from 'django.utils' (C:\Users\acer_\AppData\Local\Programs\Python\Python39\lib\site-packages\django\utils\__init__.py)

try this -- pip install --upgrade django-cors-headers pip install --upgrade djangorestframework pip install --upgrade drf_yasg

Post your pip freeze please. I suspect you have some old package versions in there.

How explained by @ Brand0R in the SO https://stackoverflow.com/a/59252857/11281707.

The Django 3.0.0 release notes specify that certain private Python 2 compatibility APIs were removed. Among those was django.utils.six.

So I've got the same problem using Python 3.9.1 with Django==3.0.7 and django-cors-headers 3.3.0 from the requirementes.txt.

Package             Version
------------------- ---------
asgiref             3.3.1
certifi             2020.12.5
chardet             4.0.0
coreapi             2.3.1
coreschema          0.0.4
Django              3.0.7
django-cors-headers 3.3.0
django-sslserver    0.19
djangorestframework 3.9.1
fcm-django          0.3.4
idna                2.10
itypes              1.2.0
Jinja2              2.11.2
MarkupSafe          1.1.1
pip                 20.3.3
pyfcm               1.4.7
pytz                2020.5
requests            2.25.1
setuptools          51.1.1
six                 1.15.0
sqlparse            0.4.1
uritemplate         3.0.1
urllib3             1.26.2

To solve this problem I found two ways: (I) downgrading Django to the last LTS version pip install Django==2.2 as sugested in SO. (II) updating django-cors-headers pip install --upgrade django-cors-headers as sugested by @aryan-jadon.
