Error in runserver with Django on windows 10 - django

I am using python 3.5 and windows 10, but had the same issue using windows 8, and that is the traceback i get while trying to runserver:

I have already tried following the instructions in the following link:
http://stackoverflow.com/questions/25714826/error-in-manage-py-runserver-with-django-on-windows-8-1
but it did not help.
This is how the lines of code look like:

(Since Im a new user I cannot paste the image to the original post)
Anyone have encountered something similar and have a solution?

I used to have similar problems because of the difficulties with the virtual environment in windows 10. Try running the powershell as an administrator and do "Set-ExecutionPolicy RemoteSigned" or "Set-ExecutionPolicy Unrestricted" if remotesigned does not work. Do this before activating the virtualenv.

first I will like you check the django version you are working with my "type python -m django --version" or "pip freeze". check weather its compatible with the python version on your pc. if it's not install compatible python version. then check weather "init.py" is within your project directory, if not add it to your project directory. then run "Set-ExecutionPolicy -Scope CurrentUser Unrestricted" on your terminal. then run activate your virtualenv, then run "python manage.py runserver"

Python Django manage.py shell Attribute error module 'ast' has no attribute 'AnnAssign'

So I'm working on this test app in Django and i wanted to add some data to my sql tables through the python shell. I ran the following command from the CMD
λ python manage.py shell
Which gave me the following output:
Traceback (most recent call last): File "manage.py", line 15, in <module>

I'm using Python 3 and Django 2.0.3.
Some things I tried on my own:
I checked that ipython was up to date using pip, my database runs on SQL community server runs and works fine and the Django server itself also runs without issues.
EDIT: I did some more digging AST is part of the standard python library. However i dont find any issues with my python install, any ideas?
EDIT2: Tried reinstalling Ipython, same traceback error.
Alright, so i did a complete reinstall of Django and Mysqlclient through PIP which solved the problem. I now have acess to the django shell.

Django manage.py commands that require input get stuck

Since a while any python manage.py command that requires an input (removing null=True without providing default, recollecting static files...) does not accept said input. when I press enter it simply displays the carriage return char ^M in the console. I have no Idea how to debug this, as ctrl+ c simply gives tracebacks like these:
./manage.py makemigrations
You are trying to change the nullable field 'package' on company to non-nullable without a default; we cannot do that (the database needs something to populate existing rows).
Please select a fix:
1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
2) Ignore for now, and let me handle existing rows with NULL myself (e.g. because you added a RunPython or RunSQL operation to handle NULL values in a previous data migration)
3) Quit, and let me add a default in models.py
Select an option: 1^M^M^M^C^CKeyboardInterrupt
The above exception was the direct cause of the following exception:

Any hints on how to approach this issue? I reinstalled my virtualenv. Maybe I should reinstall python?

I am trying to run the following command

But, getting the error

What can be the reason?

raise ValueError(error)
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>>

Why am I getting errors when trying to invoke Django Python shell?

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)

PyCharm manage.py runserver error

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:

Please note that this is all happening before I request any page from within the browser. And, as I said, I have no trouble running from Terminal. Any help would be greatly appreciated.
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
