I have been handed over an application which is built in Python - Django. I need to support it. There was no handover or anything like that. Pitty Me!
I am new to this language and framework. When I try to run the server with python manage.py runserver I get following errors:

I am unable to understand what it says. Can someone guide me over it?
I have installed all the required packages for the project with pip.
I am on Python 3.7 and using virtualenv.
UPDATE
I came to know that project works with Python 3.6, so I installed it and still getting same type of error log.

It seems to be incompatibility of Python 3.7 and your current version of Django. You can find more details in similar question
What I can suggest is to upgrade your Django 2 or use Python 3.6.
Here you can see that Python 3.7 is compatible with Django 1.11.17 version.
Can we see the code u a=have written in manage.py
Who ever tries python for the first tym they does a very basic mistake of inidnantion. Though it ll be inditnation error for sometime it will throw some other prioritized error. !CHECK FOR INDINANATION
Thanks guys for the help.
After a lot of headbang, I came to know that there were a lot of modules missing from req.txt file which were required to build the project. They were mentioned in some other file.
After installing all the required modules, and running the migrations, I was able to run the project.

Using the Azure Devops task with current setup :
task: AzureFunctionApp#1
displayName: Deploy Lab
inputs:
azureSubscription: 'serviceConnection'
appType: 'functionAppLinux'
appName: 'myAwesomeApp'
package: '.'
runtimeStack: 'PYTHON|3.8'
Also, in the root directory (ie . in the ado task), I have a requirements.txt file that contains numpy
The deployment runs successfully but when I test the app, I have the following error:
Failure Exception: ModuleNotFoundError: No module named 'numpy'
Which simply means that the requirements.txt file is not considered or pip install -r requirements.txt didn't run successfully in the remote compute, what am I doing wrong ?
EDIT: Added a step to install the packages locally did work, but as numpy is a C built library it's dependent on the host machine and that doesn't work in the remote function app :lol:
The step that I added is this one:
- bash: pip install -r requirements.txt --target="./.python_packages/lib/site-packages"
displayName: 'Install dependencies'
And the error:
Result: Failure Exception: ImportError: IMPORTANT: PLEASE READ THIS
FOR ADVICE ON HOW TO SOLVE THIS ISSUE! Importing the numpy
C-extensions failed. This error can happen for many reasons, often due
to issues with your setup or how NumPy was installed. We have compiled
some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html Please
note and check the following: * The Python version is: Python3.9 from
"/usr/local/bin/python" * The NumPy version is: "1.22.3" and make sure
that they are the versions you expect. Please carefully study the
documentation linked above for further help. Original error was: No

If using Linux, install Twisted by running pip install Twisted in terminal.
If Windows, the Twisted docs recommend pip install Twisted[windows_platform].
In both cases if you're using a virtual environment (recommended) make sure to install it inside the venv.
I am trying to create an installer for a django website that uses the django-omnibus module.
My Pyinstaller command:
pyinstaller --name djangosite manage.py
The Pyinstaller command runs to completion.
Trying to run the web server using
djangosite.exe runserver localhost:8000
I get the following error:

pkg_resources.DistributionNotFound: The 'django-omnibus' distribution was not found and is required by the application manage returned -1
If I remove all django-omnibus code, the site works fine (except for the my websocket functionality obviously). Any ideas? Thanks.
I needed to add a hook.py file for django-omnibus and add the --additional-hooks-dir=. flag to the pyinstaller command.
hook-omnibus.py
from PyInstaller.utils.hooks import copy_metadata, collect_data_files
datas = copy_metadata('django-omnibus')
datas += collect_data_files('omnibus')

I know this is a late reply, but I had a similar issue with django-user-accounts - pkg_resources.DistributionNotFound: The 'django-user-accounts' distribution was not found
I was directed here when searching for a fix. I solved the issue with the following addition to settings.py - hopefully helps someone else.

I'm new to python and hitting issues trying to use setuptools (which seems to be the recommended way to get dependencies for CI).
Following (amongst other guides) these:
http://flask.pocoo.org/docs/0.10/patterns/distribute/
https://pytest.org/latest/goodpractises.html#integration-with-setuptools-test-commands
my setup.py says:
install_requires=['Flask','Flask-SQLAlchemy'],
However when I run "setup.py test" Flask-SQLAlchemy is installed and fails:

pkg_resources.DistributionNotFound: Flask
I don't understand why it's:
a) processing the dependencies out of order
b) not finding Flask
As this is really an app rather than a library, using pip and requirements.txt is an option, however I like the standardisation setuptools brings.
Update: specifying 'Flask>=0.10.1' cures the problem - but why? There is no version of flask anywhere on the system.
Many thanks

Interestingly, if I rerun the same command as above, the installation is successful.

Quick searches on Google indicate that others have encountered variations of what I am seeing however, I couldn't locate a solution to the problem.
I had a very similar problem and found a workaround.
I also got AttributeError: 'NoneType' object has no attribute 'get_script_header'
Workaround that fixed it for me: In the list install_requires I had "tornado" before "luigi". By switching the order to "luigi" and then "tornado" this bug went away. I see that you do not use tornado or luigi, but I guess the ordering is still the cause of this problem since you can fix the problem by running your install command twice.
Additional note: Before finding this workaround I tried to upgrade to newest setuptools (v 5.8). It did not solve the bug.
I had the same problem and it was fixed by updating setuptools version, i.e.:
pip install --upgrade setuptools
