The above is for windows and not unix.

This should be: export not set.
set is a window command and doesn't or does something different under
*nix.

pubuntu@pubuntu:~/django-trunk/build/lib/django/bin/myapp1
export DJANGO_SETTINGS_MODULE=myapp1.settings
export PYTHONPATH=/usr/lib/python2.5/site-packages
django-admin.py dumpdata
Error: Could not import settings 'myapp1.settings' (Is it on sys.path?
Does it h
ave syntax errors?): No module named myapp1.settings
pubuntu@pubuntu:~/django-trunk/build/lib/django/bin/myapp1$

my settings.py has

)

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'myapp1.person',
)

pubuntu@pubuntu:~/django-trunk/build/lib/django/bin/myapp1$

I tried doing export DJANGO_SETTINGS_MODULE=myapp1.person as in
settings.py, but got same error.

I'm not the world's leading expert -- but today I've
solved the problem inside of my current python
shell using os.environ.keys()

I'll attempt to outline the basics, ">>>" indicates what
i typed on the python shell command line
"$" indicates what echoes back

>>>import os

# now to see what environment keys already exist.
>>>print os.environ.keys()
$ ['LOGNAME', 'USER', 'HOME', 'PATH',...]

# now to see whats in these environ. keys/vars
>>> print os.environ["HOME"] ## for example.
$/home/myhomefolder

# in my case the following was blank raising a nasty key error in
apocalyptic alarming red text ending with
>>>os.environ["DJANGO_SETTINGS_MODULE"]
$..."raise KeyError(key)"

# so had to set it to get moving using
# first i verified i was in my projects path
>>>os.getcwd()
$/home/myfolder/myproject'

then I issued
>>>os.environ["DJANGO_SETTINGS_MODULE"]="settings"

remember to change directories in the shell use something like.
>>>os.chdir("/home/myproject")

i hope that helps, what i'm doing is creating a *.py file I call it
simply called mydevelsets.py for loading this sort of stuff in the
shell before I start, i call it from the command line using
>>>execfile('mydevelsets.py')

i hope that helps.

# from mydevelsets.py
import os

## WTH is the current work directory anyhow
print os.getcwd()

os.chdir("/home/myproject") ## change to project directory
print os.getcwd() ## I'm from Missouri - show me!

# Set the var!
os.environ["DJANGO_SETTINGS_MODULE"]="settings"

## I'm not really from Missouri - but show me anyhow!
print os.environ["DJANGO_SETTINGS_MODULE"]

You seem to be in need of a basic Python tutorial, one which will
teach you about things like how to import modules before using them
(because, for example, you seem to be hung up on the fact that -- in
Python -- you must type "import os" before trying to use the 'os'
module).
