How can I solve the 29 unapplied migration(s) for app(s): admin, api, auth, authtoken, contenttypes, sessions, social_django

I was setting up Doccano on my desktop to perform sequence labeling tasks. I followed the instructions from a website on how to setup Doccano. Everything was working fine until I got to the last code below where I experienced migration errors.

$ git clone https://github.com/chakki-works/doccano.git
$ cd doccano
$ pip install -r requirements.txt
$ cd app
$ python manage.py createsuperuser 

This is the error below after running the last code above on git bash

You have 29 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, api, auth, authtoken, contenttypes, sessions, social_django.
Run 'python manage.py migrate' to apply them.

The error says to Run 'python manage.py migrate. When I ran the code in my terminal I got an [Errno 2] No such file or directory. Please see below. Thanks for your help.

C:\Users\okekec>python manage.py migrate
python: can't open file 'manage.py': [Errno 2] No such file or directory

Go to the folder where manage.py is and run the command there.

cd /okekec/doccano/app

ls

It should be able to see manage.py file.

Then python manage.py migrate
