django error cannot import name 'RemovedInDjango30Warning'
Solution 1
Comment out the following line:
from django.utils.deprecation import RemovedInDjango30Warning
in the files below:
python3.6/site-packages/django/contrib/admin/templatetags/admin_static.py
python3.6/site-packages/django/contrib/staticfiles/templatetags/staticfiles.py
Solution 2
This is caused by conflicts in Django versions as seen here.
ImportError: cannot import name 'RemovedInDjango30Warning'
Try uninstalling django
sudo pip uninstall django
and reinstall with a version lower than 3.0
sudo pip install django==2.2
Edit
If you wish to use different versions of Django you can use virtual environments.
First create a requirements.txt example from here
You can generate your project’s requirements by running the pip freeze command that lists all packages that are installed in your local machine with their versions.
pip freeze > requirements.txt
Do note that this process can lead to certain unnecessary packages being written to the requirements file which are installed in your local machine but not required for the project. You must manually edit the requirements file in that case.
Then create your virtual environment
Step 1 install virtualenv
pip install virtualenv
Step 2 create virtual enviroment
virtualenv env
Step 3 Activate your environment
env\Scripts\activate
When you wish to deacitvate
deactivate
Step 4 Edit your requirements.txt to have the packages you'll need for your project.
Step 5 install requirements.txt (in same dir)
pip install -r requirements.txt
Form infomation on deployment with mod_wsgi and Apache try here
Solution 3
This appears to be from a corrupt Django installation in site-packages. Remove Django and install it again.
For me, I was upgrading an existing project from Django 2.2.6 to 3.1.7. It appears that somehow files from 2.2.6 were still hanging around. I had to run pip uninstall django
twice to get back to a clean slate and then pip install django
to install the latest version.
Solution 4
This is caused by django versions. You probably upgraded it.
If you do not want to go back to version 2, create a virtual environment and do pip install django==2.2

Guys im fairly new to Django and I just started working on a personal project and decided that ill-use pycharm (i think its related to the error, or not).
when I run
python manage.py runserver
I get the error posted below. I did a bit of googling and looks like its caused by inconsistency with Django versions.I currently have Django 3.0 and I checked both globally and in the venv.
I tried to start a project outside of py charm and im running into the same issue. idk what I need to do to start using Django again. Did anyone run into this? Is this because of pycharm? If so what can I do to fix the issue?
