I'm having problem with running Django manage.py runserver on my MAC OS X Yosemite.
When I ran it soon after restarting, everything works fine. But after several minutes, the running process will stop, and when I re-rerun manage.py runserver, it will generate this error
Performing system checks...

My django version is 1.7.3, OS YOSEMITE, I had all brew updated and upgraded
Any help would be appreciated
Thanks !
There's no need to upgrade or degrade your Django version for an OSError [Error123].
I got this error for weeks and I thought about the actual reason behind this error because my code and files were all perfect! But then, after weeks of observation of my code, I figured out the hell of that mistake!
ANSWER - Please create your APPS, STATIC-FOLDER, TEMPLATE-FOLDER, and further things within your PROJECT!!
DEMONSTRATION -> { '>>' indicates next step}
OPEN POWERSHELL >> mkdir DIRECTORY_NAME >> cd DIRECTORY_NAME >> code .
this will open visual studio code within the directory named (DIRECTORY_NAME)
OPEN TERMINAL >> install django >> django startproject PROJECT_NAME >>
cd PROJECT_NAME >> python manage.py runserver >> COME OUT OF THE SERVER >> django startapp APP_NAME >> CONTINUE YOUR WORK IN THE VS CODE AND ONLY COM TO TERMINAL TO RUN SERVER.
I've managed to resolve the issue. Turns out since in this Django version I would need to separate the wsgi file for development and production use. therefore wsgi_prod.py and wsgi.py . This action was not needed in previous versions of Django.

I've been learning Python for a few months and a couple days ago i decided to learn one of Web frameworks. I found some tutorials on Django and it was looking really cool until i tried to use "runserver" command. As you can see i used the basic line "python -m django runserver manage.py" and got a lot of calls. I've just installed Django and i wasn't changing anything in it's scripts. I only started by creating a new project that worked perfectly with "python -m django startproject djangoLearn". Do you have any thoughts on how can i fix this problem? This problem prevents me from further learning beacuse i can't see my own project :((
Thanks in advance. Hope y'all have a great day.
Calls that i get while trying to run server:

I hope your virtualenv is activated ??
use this to create project django-admin startproject projectname . take note of the period it works without the period though.
use python manage.py startapp appname to create an app
don't forget to register the app in INSTALLED_APP
i think the code you want to use is python manage.py runserver
but if you use python3 use python3 manage.py runserver just use whatever you use to start your python before manage.py runserver
you should first activate your virtual environment. with a command like this in linux:
source "path-to-activate-file"
and command like this in windows:
\pathto\env\Scripts\activate
This might seem like an already asked question but I have searched for an answer for a week now and got nothing.
The problem is I have developed an API using Django which is hosted on a server. Now when I run the following command to initiate the server :
python manage.py runserver 0.0.0.0:9000
The server starts as usual. Its only when I send request to the server via "Postman" that I see the following error:
FileNotFoundError: [Errno 2] No such file or directory: 'manage.py'
The strange thing is there is no error in running the server but only when I send a request to it. Also I have many more Django APIs running on the same server with same python version(Python 3.4.3) and same virtual environment (but different port) that are running just fine.

Things I have tried:
I have tried changing the !# as suggested on various posts.
I have tried using dos2unix to convert the file to unix format(server on which my API is hosted is linux based).
I even have tried to create a new Django project.
And yes I'm running manage.py from the correct directory.
I have also tried making manage.py executable by :
chmod +x manage.py
Nothing worked for me so far. Am I missing something?
I've just recently started played around with web application development using Django and now got to Django-Q for async tasks.
I followed this tutorial up to slide 13. Unfortunately then, when I try to run python manage.py qcluster I get these error messages:

I'm using a Windows 7 machine and Python 3.5.1 (32 bit) with following requirements:
appdirs==1.4.3
arrow==0.10.0
blessed==1.14.1
Django==1.9
django-picklefield==0.3.2
django-q==0.7.18
future==0.16.0
packaging==16.8
pyparsing==2.2.0
python-dateutil==2.6.0
six==1.10.0
wcwidth==0.1.7
I tried looking up the source of the error, it looks to me as it might not be exclusively related to Django or Django-Q. Other than that I don't really understand what it means.
Also tried with Python 2.7.12, outside of a virtualenv, there I get a TypeError: can't pickle _thread.lock objects, which I don't really get either.
Any ideas how to solve this?
[Edit]
After experimenting with a DjangoQ alternative - Celery - I as able to recreate the problem:
The same error occurs if using Celery 4.0.2, but not with Celery 3.1.25
I still haven't figured out how to fix this, but decided to stick to Celery for the time being, since it kinda works...
Install the latest version with pip:
$ pip install django-q
Add django_q to INSTALLED_APPS in your projects settings.py:
INSTALLED_APPS = (
# other apps
'django_q',
)
Run Django migrations to create the database tables:
$ python manage.py migrate
Choose a message broker , configure it and install the appropriate client library.
Run Django Q cluster in order to handle tasks async:
$ python manage.py qcluster

I'm the maintainer of the package, thanks to your post I realized that we were missing celery/django-celery in our requirements. It's now added in the latest version.
So "pip install django-audiofield" will install those dependencies for you.
If you have django-audiofield already installed you can run the following command to upgrade : "pip install django-audiofield --upgrade"
Have you installed celery? If no, install celery (pip install celery). If the github application in question (a link would have been nice) has a requirements.txt file anywhere, do pip install -r requirements.txt to install all the required dependencies of the application.
If yes, it looks like your import search path may not be set up correctly to find Celery - just a guess based on the import error.
Open up the django shell (type python manage.py shell when you're in your project's working directory) and type in import sys; print sys.path. Make sure that Celery is installed in one of those directories, since sys.path specifies the import search path for python modules.
If it isn't included there, you can temporarily append the directory celery is installed into by doing sys.path.append("<directory where celery is>") (mind the backslashes, since you're on Windows). If, after doing that, you can successfully from celery.tasks import Task, then you can set the PYTHONPATH environment variable appropriately to make it permanent.
Also, since you installed Celery into a virtualenv, it may be worth checking that both django and Celery are in the same virtualenv.
Finally, the latest commits to Celery indicate Celery now has native Django support, but since that hasn't been released as a stable version yet, you may want to look at django-celery.
Edit (in response to comment below):
Since you mentioned you're trying to get django-audiofield to work: it seems to be on pypi. This means you can use pip (or easy_install) to install it using pip install django-audiofield once you've installed all the required (non-python) dependencies, and stuff like celery should be downloaded for you.
I decided to try developing on python with django, while python is new to me right now.
[I'm using Windows 7 64bit]
Then, i installed python 2.7, added C:\Python27\;C:\Python27\Scripts; to PATH variable.
Next, i installed Eclipse Classic (last version) and installed PyDev, and Django.
I created my first project on Eclipse as a Django project but couldn't run it.
I'm trying (Right click on my project)-> Run as -> PyDev: Django, and i have the following console log:

and the list goes on...
So i tried to run the project with the python console, using:
import Django
manage.py runserver
and i have the following syntax error:
File "<stdin>", line 1
manage.py runserver
^ SyntaxError: invalid syntax
What is the problem with running my project ? How can i solve this?
Thanks.
Edit:
After trying to run the project with the following command:

You must be in the project directory to run the python manage.py runserver command. You also need to (1) set the PYTHONPATH environment variable to include your project directory's parent and (2) set the DJANGO_SETTINGS_MODULE environment variable to yourproject.settings
