Django 1.6: settings file not found no matter what - django

Question

I searched deep and wide, but no solution has worked so far.
I'm trying this with Django 1.6 in my virtual environment. In my manage.py file I have the following line:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproj.settings")
With this, when I execute python ./manage.py runserver I get the traceback:
Traceback (most recent call last):
File "./manage.py", line 9, in <module>
execute_from_command_line(sys.argv)
File "/home/int/.local/lib/python2.7/site-packages/django/core/management/__init__.py", line 453, in execute_from_command_line
utility.execute()
File "/home/int/.local/lib/python2.7/site-packages/django/core/management/__init__.py", line 392, in execute
self.fetch_command(subcommand).run_from_argv(self.argv)
File "/home/int/.local/lib/python2.7/site-packages/django/core/management/__init__.py", line 263, in fetch_command
app_name = get_commands()[subcommand]
File "/home/int/.local/lib/python2.7/site-packages/django/core/management/__init__.py", line 109, in get_commands
apps = settings.INSTALLED_APPS
File "/home/int/.local/lib/python2.7/site-packages/django/conf/__init__.py", line 53, in __getattr__
self._setup(name)
File "/home/int/.local/lib/python2.7/site-packages/django/conf/__init__.py", line 48, in _setup
self._wrapped = Settings(settings_module)
File "/home/int/.local/lib/python2.7/site-packages/django/conf/__init__.py", line 134, in __init__
raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'myproj.settings' (Is it on sys.path?): cannot import name current_app
Then I added
sys.path.insert(0, '/home/int/Documents/myproj/myproj'), where the modules are
to my manage.py file and got the same traceback as above.
If I try relative import, i.e. changing that line in manage.py to
os.environ.setdefault("DJANGO_SETTINGS_MODULE", ".myproj.settings")
I get the error
TypeError: relative imports require the 'package' argument
The file settings.py is definitely in /home/int/Documents/myproj/myproj (triple-checked).
So I don't know how to solve this seemingly simple issue. Would appreciate some help with it.
