Full Error: Could not import 'rest_framework_jwt.authentication.JSONWebTokenAuthentication' for API setting 'DEFAULT_AUTHENTICATION_CLASSES'. ImportError: cannot import name 'smart_text' from 'django.utils.encoding'

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    ),
}

And this is the pip freeze in the virtual env:

in the middle of the error, it addresses some lines across views.py for decorators:

from http.client import HTTPResponse
from multiprocessing import context
from django.shortcuts import render
from django.http import HttpResponse, Http404, JsonResponse
from .models import Tweet
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticated
from rest_framework.decorators import api_view, permission_classes
from rest_framework import status

I'm not sure if they're even related

'rest_framework_jwt.authentication.JSONWebTokenAuthentication' this is provided by djangorestframework-jwt wich is not not being maintained anymore . Just uninstall it instead use 'rest_framework_simplejwt.authentication.JWTAuthentication' that comes from djangorestframework-simplejwt

1 - install djangorestframework-simplejwt : pip install djangorestframework-simplejwt

2- Your 'DEFAULT_AUTHENTICATION_CLASSES' should be like this :

'DEFAULT_AUTHENTICATION_CLASSES': (
    
    'rest_framework.authentication.SessionAuthentication',
    'rest_framework.authentication.BasicAuthentication',
    'rest_framework_simplejwt.authentication.JWTAuthentication', 
),

3 - in your root urls.py file (or any other url config), include routes for Simple JWT’s TokenObtainPairView and TokenRefreshView views:

from rest_framework_simplejwt.views import (
    TokenObtainPairView,
    TokenRefreshView,
)

urlpatterns = [
    ...
    path('api/token/', TokenObtainPairView.as_view(), name='token_obtain_pair'),
    path('api/token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
    ...
]
