I tried to install django on my shared hosting environment, which has SSH access.
I downloaded the newest version of Django using
svn export http://code.djangoproject.com/svn/django/trunk/django django
I can import Django in python shell without any error throwing.
But then I tried to start a new project using django-admin.py and it started throwing me a bunch of error, in which I tried to google for the past few hours. I still can't find it
Below is the actual error:
k4660061#server42222:~$ django-admin.py startproject klikevent

Thanks
UPDATE
After a good night sleep, I got it working! See answer by Bernie. I have to see the stacktrace over and over, but I just need to add the import statement to multiple file
the file are
django/utils/archive.py
django/core/management/templates.py
and any file that throw the warning with_statement
Thanks #Bernie
If the syntax error is related to the with statement, it could be that your prod server has an older version of Python than your dev server.
If your prod server is running version 2.5 or higher you can do this:
from __future__ import with_statement
Please note: any from __future__ imports must be the very first import.

I have an old DJango application that used work fine but suddenly crashes. I use to test it with:
cd /opt/formshare/src/formshare/
export PYTHONPATH=$PYTHONPATH:/opt/formshare/src/formshare
export DJANGO_SETTINGS_MODULE=formshare.settings.default_settings
python manage.py validate
But now I get this error:

I tried to add set the path and setting in the validate but nothing works.
Any idea what could have changed and how to correct it?
The django process doesn't appear to be seeing your formshare.settings.default_settings. Without seeing the project structure, it's hard to know exactly what's going on, but a few things you might check.
If you are using python 2.x, does the formshare/ and the settings/ directory both have an __init__.py file in them?
Try adding /opt/formshare/src/ to the python path instead of (or in addition to) what you have.
One trick that I often try to make sure the python path is correct: while I'm active in my virtualenv, I'll enter a python shell (not django shell) and try something like the following:
import formshare
from formshare import settings
from fomrmshare.settings import default_settings
The error messages that might be generated from those might also help isolate the issue.
Since you activated virtualenv, you have to do something different. Try add2virtualenv in virtualenvwrapper.For more info

I have a Django application, which very suddenly started giving me an error. I made a code change, restarted the application, and now I can't get rid of this error. I really don't think that I did anything else in between the two runs.
The error is ImportError: "No module named unittest" I don't know if it thinks it should be running a unit test or if this just happens to be the first thing to fail.
I have tried running it both from Eclipse and from the CMD line with manage.py runserver. Same error. (This is an update. previously I had only tried from Eclipse.) A brand-new project made in Eclipse has the same error.
This happens with any web application (using runserver), so it's not my code. I also reverted back to older code that worked fine before.
I have tried restarting my computer.
I am able to run "regular'(not a web application) python programs from the cmd line. So it does find Python.
I honestly have no idea what to do at this point, except to reinstall Python, which I'd like to avoid. Anyone?
NEW Stack trace (Update: previous was from Eclipse and just showed pydev errors. Run from cmd line it shows more python.)

Well, don't know if I'd call it an answer, but I reinstalled Python and now it's working. Now I just have to reinstall my 10 or so libraries to fix the runtime errors.
unittest module is integral part of python, which causes import error when django tries to import it. You must have somehow deleted some python package, or have corrupted installation.
I need to ask because I'm starting in Django and it was impossible for me to continue with the tutorial that I'm following. I've just completed a Python course, I know the basics of python. The case is that I've installed Django in my mac and it's OK because when I do in the IDLE the
import django
print django.VERSION
It makes a good answer without errors in IDLE (is the software that I use to write python code). But when I execute in the Terminal the command:
python manage.py runserver
It raises this error:

I also want to ask you some questions:
Can I use XAMPP instead of Django? How?
What is Django used for exactly?
I've installed PyDev in Eclipse. How can I set Django to execute code properly?
call command django-admin startproject xxx under the target directory. You can get three .py files: setting.py, urls.py and manage.py. And you can execute python manage.py runserver command
I think it's slightly outdated now, but I'd seriously recommend going through the Djangobook examples. It'll explain how to set up Django properly, and give a pretty good foundation in how to use it.
I am using python django on windows,and trying to deploy to heroku . When i tried to install psycopg2 using pip,
pip install psycopg2
i got error :
unable to find vcvarsall.bat
Then i found that i need to install visual studio 2008 (or) i can directly download and install compiled version , so downlaoded from this link :
http://www.lfd.uci.edu/~gohlke/pythonlibs/
Filename i downloaded : psycopg2-2.4.5.win32-py2.7.exe
Even after installing this i am getting error : no module named psycopg2.extensions
So, what more should i do ?

While isntalling psycopg2 both by pip and easy_install, installdidnt work as i got this error : unable to find vcvarsall.bat with some msg : no previsouly included directores matching 'doc\src_build'
Thanks
Despite some claims on the Internet, psycopg2 DOES work in a VirtualEnv.
Download the correct version of win-psycopg2. Typically I use 32-bit Python 2.7 so I got psycopg2-2.4.5.win32-py2.7-pg9.1.3-release.exe.
You CANNOT install this file into a VirtualEnv, but you can rename the .exe file to .zip and open with a utility like 7-Zip. You will get a folder called “psycopg2″ and a file called “psycopg2-2.4.5-py2.7.egg-info”. Copy these into:
[...]\Envs\MyVirtualEnv\Lib\site-packages
This worked for me, hope it works for you.
Take a look at http://slacy.com/blog/2010/09/python-unable-to-find-vcvarsall-bat/. It seems you need to install Microsoft Visual Studio Express to solve the vcvarsall.bat issue.
Pretty crazy...
Binaries from this link:
http://www.stickpeople.com/projects/python/win-psycopg/
In settings.py it should look like this in db settings
'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
You CANNOT install this file into a VirtualEnv, but you can rename the .exe file to .zip and open with a utility like 7-Zip. You will get a folder called “psycopg2″ and a file called “psycopg2-2.4.5-py2.7.egg-info”. Copy these into:

Yes, this work!
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:

So i tried to run the project with the python console, using:
import Django
manage.py runserver
and i have the following syntax error:

What is the problem with running my project ? How can i solve this?
Thanks.

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

c:\temp> python

the settings module that is imported should then be the one in your project directory...
