ImportError: cannot import name RemovedInDjango19Warning

问题

I'm on Django 1.8.7 and I've just installed Django-Allauth by cloning the repo and running pip install in the app's directory in my webapp on the terminal. Now when I run manage.py migrate, I get this error:

➜src git:(master) ✗ python manage.py migrate
    Traceback (most recent call last):

I've checked and I'm still on django 1.8.7 so it wasn't accidently upgraded.

回答1:

@MaxRah This is caused by conflicts in Django versions. As mentioned by others, you will have to remove pip uninstall django and reinstall your preferred version: pip install django==1.9 This should resolve the issue.

I was getting this error while trying to use cron-jobs on python (using kronos library)

#getting error while trying to run kronos cron job
python manage.py runtask complain

as @ olivrg metioned this fixed the issue (reinstall django in my case i was using version 1.8.X so i upgraded to 1.9X)

sudo pip uninstall django

sudo pip install django==1.9

Your installation is corrupt, your traceback does not match the code from version 1.8.7 (from importlib import import_module is on line 8, not line 4). You need to uninstall Django and do a clean install.

I would highly recommend to set up a virtual environment for your Django project, using virtualenv. This is a de facto standard to separate different python environments on your system. The corruption likely occurred because different projects tried to install different versions of Django in your system-wide site packages.
