How to upgrade django?
PythonDjangoPython Problem Overview
My project was running on Django 1.5.4 and I wanted to upgrade it. I did pip install -U -I django and now pip freeze shows Django 1.6.5 (clearly django has upgraded, I'm in virtualenv) but my project is still using Django 1.5.4. How can I use the upgraded version?
UPDATE: Thanks for your comments. I tried everything but unfortunately nothing worked and I had to re-deploy the app.
Hope someone explains why this happened.
Python Solutions
Solution 1 - Python
You can use --upgrade with the pip command to upgrade Python packages.
pip install --upgrade django==3.3.1
Solution 2 - Python
I use this command for upgrading any package using pip:
pip install <package-name> --upgrade
Example: pip install django --upgrade
you need to use the --upgrade or -U flag for upgrading.
Alternatively, you can use python -m pip install -U Django.
Solution 3 - Python
- Use this command to get all available Django versions:
yolk -V django - Type
pip install -U Djangofor latest version, or if you want to specify version then usepip install --upgrade django==1.6.5
NOTE: Make sure you test locally with the updated version of Django before updating production.
Solution 4 - Python
You can use pip install -U django. It will update to the current stable version. Read official documentation on Django Docs
Solution 5 - Python
with python 3.7 try:
sudo pip3 install --upgrade django==2.2.6
Because using the following:
pip3 install -U django
or with python 2.7 if you like to keep that old python:
pip install -U django
Only gives you the older version of django (1.11.xx instead of 2.2.6)
Solution 6 - Python
pip install --upgrade django
works just fine, but before upgrading it's highly recommended to read this part from the documentation: https://docs.djangoproject.com/en/2.1/howto/upgrade-version/
Solution 7 - Python
I'm not an expert on either Python or Django.
What I am doing is following along this really very good book: Test Driven Web Development With Python (2nd Ed). It uses Django...
I'm also using a Windoze machine (W10) with Cygwin.
The reason I mention all this is because I found, having installed Python 3.6 in my Cygwin setup, that I had to use pip3, not pip, to install Django.
My installed version of Django was 1.11.8. To follow the "official" (?) tutorial here they want you to have Django 2.0 installed. I successfully managed to do this with:
$ pip3 install -U django
Hope this helps someone. Perhaps someone much more knowledgeable than me can talk about the need or otherwise to use pip3 for all Python 3.x activity???

How to upgrade Django Version
python -m pip install -U Django
> use cammand on CMD
Solution 9 - Python
sudo pip install --upgrade django
also upgrade the DjangoRestFramework:
sudo pip install --upgrade djangorestframework
Solution 10 - Python
The method outlined in the docs is correct -
https://docs.djangoproject.com/en/3.0/howto/upgrade-version/
What I can add to the above answers is the rationale. If you're very far behind in Django versions (ex. 1.5 -> and you want to go to 2.0) the developers only want you to upgrade one step at a time. ex. 1.5 -> 1.6 -> 1.7 etc.
The purpose being that this limits the amount of things that break on upgrading. You should include the -Wa warning flags every time you upgrade a step, so you can fix deprecated features before they are removed in future upgrades.
A feature is generally deprecated for a couple of versions, and then removed entirely. So this gives you the ability to keep the app stable while upgrading.
Solution 11 - Python
You can use the upgraded version after upgrading.
You should check that all your tests pass before deploying :-)
Solution 12 - Python
I think after updating your project, you have to restart the server.
Solution 13 - Python
You can use this command in vitualenv:
`pip install django==<version>`
this should work.
Solution 14 - Python
you must do the following:
1- Update pip
python -m pip install --upgrade pip
2- If you already install Django update by using the following command
pip install --upgrade Django
or you can uninstall it using the following command
pip uninstall Django
3- If you don't install it yet use the following command
python -m pip install Django
4- Type your code
Enjoy
Solution 15 - Python
From the Django Docs: if you are using a Virtual Environment and it is a major upgrade, you might want to set up a new environment with the dependencies first.
Or, if you have installed Django using the PIP, then the below is for you:
python3.8 -m pip install -U Django .
Solution 16 - Python
I have the same issue, when I upgraded my ubuntu 18.04 to 20, by default in the latest version of ubuntu django=2.2.12 pre-installed, but I'm working on the latest Django version=3.1, so I need to upgrade that to 3.1.
Here is a solution:
python 3.8.5
sudo pip3 install --upgrade django==3.1.7
Now check your all pre-installed versions with python
pip list
Solution 17 - Python
pip3 install django -U
this will uninstall django, and then install the latest version of django.
pip3 is if you use python3.
-U is shortcut for --upgrade
Solution 18 - Python
new version in django :-
pip install Django==4.0.2
