I've been developing a Django app for weeks locally on OSX 10.6.3. Recently, I rebooted my machine and went to start my development environment up.

Here's the error:

cm:myApp cm$ python manage.py runserver
Traceback (most recent call last):
File "manage.py", line 11, in execute_manager(settings)
File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 360, in execute_manager
setup_environ(settings_mod)
File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 343, in setup_environ
project_module = import_module(project_name)
File "/Library/Python/2.6/site-packages/django/utils/importlib.py", line 35, in import_module import(name)
ImportError: No module named myapp

I'm pretty new to Django / Python.

Digging around, it's possible that this might be due to MacPorts. Initially, I had a rough time getting Django up and running and I no longer remember if I'm using the Django from a MacPorts install or from easy_install. How do I tell? (I'd prefer not to reinstall everything).

Also, why is the camel casing in my app name gone in the ImportError message? When I search for "myapp" in my django project, I don't find it without camelcase anywhere.

And what causes MacPorts to work for a while but then break?

As a few other details, from settings.py:

INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'south', 'registration', 'pypaypal', 'notifier', 'myApp.batches', )
