Calling python manage.py migrate results in the following error for the auth table. I've tried deleting my DB and all migrations to start from scratch, not sure where the issue is coming from. Django version is 4.1
$ python manage.py migrate

There is some issue with Django 4.1. Uninstall django and reinstall it with 4.0. This solved it for me.
pip uninstall django
pip install django==4.0

I am trying to remove some fields from existing model of Django on Heroku, So I run make migrations, then migrate commands, it seemed like succesfully did the migrations.
After that I found out one field was missing, so I created next migration file myself, put dependency to previous auto generated migration file. When I run it, I have an error like this:
~ $ python manage.py migrate

You can go to the migrate folder and delete all .py files except __init__.py.
After that, run:
python manage.py makemigrations
I want to install djangocms_table plugin.My current Django cms version is 3.5.2
I followed the below steps to do the same.
1.pip install djangocms_table
2.Added 'djangocms_table' to INSTALLED_APPS
3.manage.py migrate djangocms_table
After I ran migrate command got the below exception.
System check identified some issues:

django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: djcelery
I'm using django version 1.7.5 and celery version 3.1.17. In the sample code, only djcelery app is added in the app list in settings.py .
I think that I had the same problem. I tried to find duplicate names on installed apps and even modules named djcelery inside other packages. Didn't find anything to help. In my case, the app was running fine in some machines, but was failing in others. I could even make it run, but migrate kept failing.
What solved my problem was to reinstall all my pip packages. Supposing that you have all your packages listed in a file requirements.txt:
pip uninstall -r requirements.txt
and then
pip install -r requirements.txt
I think this problem may be caused by a dead pyc or a bad dependency chain. I also found a problem with mysql for python being installed partially by pip and part by apt-get (running on Ubuntu). You can check this running your command like:
python -m pdb manage.py migrate
The error reported by pdb was related to a bad connection. Without pdb I had the same message as yours.
Tested on Ubuntu with Python 2.7.6, pip 6.1.1, django 1.7, celery 3.1.8, django-celery-3.1.16.
The problem definitely stems from the fact that djcelery appears in both unmigrated and migrated apps. From what I've seen this is usually symptomatic of having both south and django style migrations in the same app. In any case likely something is off with djcelery's migrations directory.
When I try to migrate my db, I'm getting this error:
Running migrations for easy_thumbnails:
- Nothing to migrate.
- Loading initial data for easy_thumbnails.

It's looks like not easy_thumbnails problem, because when I try to migrate my django-allauth it raises the same error.
Please, help me!
It seems like your django package was broken. Check that there is python2.7/site-packages/django/db/models/loading.py file in your environment. Or just reinstall django package.
pip install -U --force-reinstall django
I´m having a issue when I ran "python manage.py rebuild_index" in my app supported by haystack and elasticsearch.
Python 2.7
Django version 1.6.2
Haystack 2.1.0

just do

If you just install requests module through pip this error should go away.
