I'm relatively new to Django and programming, so I have no idea what caused this error or how to fix it. I asked another question related to the same error but got no responses so here's a simpler version.
When I run Django-admin check (along with various other commands not including run server) I get the following error.
django.core.exceptions.ImproperlyConfigured: Requested setting LANGUAGE_CODE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
I have spent hours googling and nothing I find works (I either get this error or a module not found error). What can I do?
here's the full traceback:

Edit: I get the module not found error (no module named ) when I set the Django settings module
The problem is that Django cannot find your settings.py file to run the app. You need to set the environment variable DJANGO_SETTINGS_MODULE to point to you settings.py or if you're using an IDE just add it to your project config.

I am trying to run the following command
python manage.py makemigrations
But, getting the error
ValueError: path is on mount 'C:', start on mount 'F:'
What can be the reason?

ValueError: path is on mount 'C:', start on mount 'F:'
The error is occurring because Django is trying to find a relative path between 2 directories and they do not exist (since they are on different drives). This issue is mentioned here: https://bugs.python.org/issue7195. But this response helps to understand the problem: https://bugs.python.org/msg94780.
os.relpath does give you a relative path between two directories.
The problem you are encountering is that, on Windows, a relative path
doesn't even exist if the two directories are on different drives
(which is exactly what the error message says).
When I ran into this error, I was trying to make a migration file for my own app that is located on the F: drive. Running:
python.exe .\manage.py makemigrations
had Django scanning for every change. It located a change for djcelery. This is located in a virtual environment on my C: drive.
To fix this, I just added the app name when calling makemigrations:
python.exe .\manage.py makemigrations <<app_name>>
My current version of python is 2.7.10 and version of Django is 1.9.1, path.py is 8.1.2 but every time when I'm trying to invoke python shell by command:
$ python manage.py shell I'm getting a lot of errors and the ending of them looks like:

How can I overcome the problem?
From doing a quick search, it looks like this error happens when both Django and IPython are installed, since apparently Django will attempt to use the IPython shell.
The first resource with someone who had a similar issue:
run python manage.py shell occurs errors
And in the link above, one of the comments on the OP's question suggested looking at this separate thread for answers:
https://superuser.com/questions/318655/error-running-ipython3-on-xp-typeerror-isdir-takes-exactly-1-argument-0-gi
The winning answer says the following:
Finally decided to give this another stab, and managed to get it to
work. The solution is a two-line change in the
ipython-0.11-py3.2.egg\IPython\utils\pickleshare.py file, line 52:
Before:
if not self.root.isdir():
self.root.makedirs()
After:
if not os.path.isdir(self.root):
os.makedirs(self.root)
I recently upgraded my Ubuntu to 14.04, and consulted this question to solve my erros, ImportError: No module named _io in ubuntu 14.04. That was solved perfectly.
I also checked out this question as it's similar to mine, Consistently getting ImportError: Could not import settings 'myapp.settings' error, but could not use the same solution.
I do not use manage.py in my project and I have done numerous exports of the PYTHON_PATH to no end of my issues. Here is my traceback;

I found the problem:
The was an issue with the egg files during the virtualenv reinstall. Though the programs were there, they couldn't be found. I just performed another install of the requirements to refresh the egg info.
I have a Django app that successfully ran on Heroku and uses mongodb engine. All of a sudden, I can not push it anymore. It does not seem to recognize the django_mongodb_engine module anymore. I even reverted all changes to the version that last ran, but it's still the same. I suspect a version conflict or so, but can not figure out how to fix it.
This is the error I'm getting:

And these are the important parts from the requirements.txt:

I'm especially confused because I reverted all changes. Exactly this code with the same configuration ran perfectly (and still does on my production server), just pushing does not work.
Thanks
Simon
Of course, just when I asked on SO I figure out the answer :-)
I don't know why exactly, but defining the exact revision that i want to check out solved the problem.
So the requirements.txt looks now like this:

Sorry to ask a noob question but I have no idea why this is happening.
I've just reinstalled Django 1.3, and am trying PyCharm for the first time. When I run python manage.py runserver from Terminal everything goes without a hitch, however if I try to runserver from within PyCharm I get the following:

What version fo pycharm are you using ? Actually it`s a error in django 1.3. It will occur if you try to run django from any ide in reload mode. It can be fixed by patching django. Although PyCharm should automatically switch to no reload mode.
Read this : http://blogs.jetbrains.com/pycharm/2011/03/pycharm-1-2-1-release-candidate-py-test-2-0-buildout-1-5/
Apply the patch. Its Django 1.3.1 error. This worked for me on pYCharm 3.4.1
