如何检查Django版本

I have to use Python and Django for our application. So I have two versions of Python, 2.6 and 2.7. Now I have installed Django. I could run the sample application for testing Django succesfuly. But how do I make sure whether Django uses the 2.6 or 2.7 version and what version of modules Django uses?

Django 1.5 supports Python 2.6.5 and later.

If you’re under Linux and want to check the Python version you’re using, run python -V from the command line.

If you want to check the Django version, open a Python console and type

>>> import django
>>> django.VERSION
(2, 0, 0, 'final', 0)

Basically the same as bcoughlan’s answer, but here it is as an executable command:

$ python -c "import django; print(django.get_version())"
2.0

If you have installed the application:

$ django-admin.py version
2.0

Go to your Django project home directory and do:

./manage.py --version

>>> import django
>>> print(django.get_version())
1.6.1

I am using the IDLE (Python GUI).

If you have pip, you can also do a

pip freeze

You can pipe it through grep to get just the Django version. That is,

josh@villaroyale:~/code/djangosite$ pip freeze | grep Django
Django==1.4.3

For Python:

import sys
sys.version

For Django (as mentioned by others here):

import django
django.get_version()

The potential problem with simply checking the version, is that versions get upgraded and so the code can go out of date. You want to make sure that ‘1.7’ < ‘1.7.1’ < ‘1.7.5’ < ‘1.7.10’. A normal string comparison would fail in the last comparison:

>>> '1.7.5' < '1.7.10'
False

The solution is to use StrictVersion from distutils.

>>> from distutils.version import StrictVersion
>>> StrictVersion('1.7.5') < StrictVersion('1.7.10')
True

As you say you have two versions of python, I assume they are in different virtual environments (e.g. venv) or perhaps conda environments.

When you installed django, it was likely in only one environment. It is possible that you have two different versions of django, one for each version of python.

In from a Unix/Mac terminal, you can check your python version as follows:

$ python --version

If you want to know the source:

$ which python

And to check the version of django:

$ python -m django --version

There are various ways to get the Django version. You can use any one of the following given below according to your requirements.

Note: If you are working in a virtual environment then please load your python environment

Terminal Commands

1. python -m django --version
2. django-admin --version or django-admin.py version
3. ./manage.py --version or python manage.py --version
4. pip freeze | grep Django
5. python -c "import django; print(django.get_version())"
6. python manage.py runserver --version

Django Shell Commands

1. import django django.get_version() OR django.VERSION
2. from django.utils import version version.get_version() OR version.get_complete_version()
3. import pkg_resources pkg_resources.get_distribution('django').version

(Feel free to modify this answer, if you have some kind of correction or you want to add more related information.)

For checking using a Python shell, do the following.

>>>from django import get_version
>>> get_version()

If you wish to do it in Unix/Linux shell with a single line, then do

python -c 'import django; print(django.get_version())'

Once you have developed an application, then you can check version directly using the following.

python manage.py runserver --version

django-admin --version
python manage.py --version
pip freeze | grep django

Django will use the version of Python specified by the PYTHONPATH environment variable. You can use echo $PYTHONPATH in a shell to determine which version will be used.

The module versions used by Django will be the module versions installed under the version of Python specified by PYTHONPATH.

run pip list on LINUX TERMINAL and find Django and its version on list

run pip freeze on cmd on Windows

You can do it without Python too. Just type this in your Django directory:

cat __init__.py | grep VERSION

And you will get something like:

VERSION = (1, 5, 5, 'final', 0)

There is an undocumented utils versions module in django

https://github.com/django/django/blob/master/django/utils/version.py

With that you can get the normal version as string or a detailed version tuple:

>>> from django.utils import version
>>> version.get_version()
... 1.9
>>> version.get_complete_version()
... (1, 9, 0, 'final', 0)

Django version or any other package version

open the terminal or command prompt

type

pip show django

or

pip3 show django

you can find any package version…
example

pip show tensorflow

pip show numpy 

etc….

Type in your CMD or terminal:

python -m django --version

I thought the most pythonic way was:

>>> import pkg_resources; 
>>> pkg_resources.get_distribution('django').version
'1.8.4'

This ties directly into setup.py: https://github.com/django/django/blob/master/setup.py#L37

Its definitely the best way to get the version number of ANY package!

Also there is distutils

>>> from distutils.version import LooseVersion, StrictVersion
>>> LooseVersion("2.3.1") < LooseVersion("10.1.2")
True
>>> StrictVersion("2.3.1") < StrictVersion("10.1.2")
True
>>> StrictVersion("2.3.1") > StrictVersion("10.1.2")
False

As for the python version, i agree with @jamesdradbury

>>> import sys
>>> sys.version
'3.4.3 (default, Jul 13 2015, 12:18:23) \n[GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)]'

Tying it all together:

>>> StrictVersion((sys.version.split(' ')[0])) > StrictVersion('2.6')
True

If you want to make Django version comparison, you could use django-nine (pip install django-nine). For example, if Django version installed in your environment is 1.7.4, then the following would be true.

from nine import versions

versions.DJANGO_1_7 # True
versions.DJANGO_LTE_1_7 # True
versions.DJANGO_GTE_1_7 # True
versions.DJANGO_GTE_1_8 # False
versions.DJANGO_GTE_1_4 # True
versions.DJANGO_LTE_1_6 # False

Type the following command in Python shell

import django
django.get_version()

After django 1.0 you can just do this

$ django-admin --version
1.11.10

You can get django version by running the following command in a shell prompt

python -m django –version

If Django is installed, you should see the version otherwise you’ll get an error telling “No module named django”.

you can import django and then type print statement as given below to know the version of django i.e. installed on your system:

>>> import django
>>> print(django.get_version())
2.1

Python version supported by Django version

Django version     Python versions
1.0                2.3, 2.4, 2.5, 2.6
1.1                2.3, 2.4, 2.5, 2.6
1.2                2.4, 2.5, 2.6, 2.7
1.3                2.4, 2.5, 2.6, 2.7
1.4                2.5, 2.6, 2.7
1.5                2.6.5, 2.7 and 3.2.3, 3.3 (experimental)
1.6                2.6.5, 2.7 and 3.2.3, 3.3
1.11               2.7, 3.4, 3.5, 3.6, 3.7 (added in 1.11.17)
2.0                3.4, 3.5, 3.6, 3.7
2.1, 2.2           3.5, 3.6, 3.7

To verify that Django can be seen by Python, type python from your shell. Then at the Python prompt, try to import Django:

>>> import django
>>> print(django.get_version())
2.1
>>> django.VERSION
(2, 1, 4, 'final', 0)

Simply type python -m django --version or type pip freeze to see all the versions of installed modules including Django.
