No module named 'rest_framework' on pythonanywhere.com - django

Question

I'm trying to host my Django app on https://pythonanywhere.com
I'm am getting the following error :
ModuleNotFoundError: No module named 'rest_framework'
I tried
pip install djangorestframework
pip3 install djangorestframework
but its is still showing error.
I also tried pip freeze and found djangorestframework==3.13.1 in the list.
>>> import rest_framework
also works fine.
I ran my project locally and also it in a new virtual env, it worked fine. Installed same requirements.txt on pythonanywhere but still the same error.
This is bugging me for a long time! please help
here is my error log file:

Answer 1

I was not using a virtual environment but using one and configuring it worked.
