python - django tutorial no module named staticfilespolls error -

i had done first part of tutorial, got stuck, realized there several versions of tutorial, deleted polls , mysite directories , started again. however, when run

$ python manage.py sql polls result is:

     c:\python27\scripts\mysite>python manage.py sql polls traceback (most recent call last):   file "manage.py", line 10, in <module>     execute_from_command_line(sys.argv)   file "c:\python27\lib\site-packages\django\core\management\__init__.py", line 399, in execute_from_command_line     utility.execute()   file "c:\python27\lib\site-packages\django\core\management\__init__.py", line 392, in execute     self.fetch_command(subcommand).run_from_argv(self.argv)   file "c:\python27\lib\site-packages\django\core\management\base.py", line 242,  in run_from_argv     self.execute(*args, **options.__dict__)   file "c:\python27\lib\site-packages\django\core\management\base.py", line 280,  in execute     translation.activate('en-us')   file "c:\python27\lib\site-packages\django\utils\translation\__init__.py", lin e 130, in activate     return _trans.activate(language)   file "c:\python27\lib\site-packages\django\utils\translation\trans_real.py", l ine 188, in activate     _active.value = translation(language)   file "c:\python27\lib\site-packages\django\utils\translation\trans_real.py", l ine 177, in translation     default_translation = _fetch(settings.language_code)   file "c:\python27\lib\site-packages\django\utils\translation\trans_real.py", l ine 159, in _fetch     app = import_module(appname)   file "c:\python27\lib\site-packages\django\utils\importlib.py", line 40, in im port_module     __import__(name) importerror: no module named staticfilespolls 

in settings.py

installed_apps = (     'django.contrib.admin',     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.messages',     'django.contrib.staticfiles'     'polls', )  databases = {     'default': {         'engine': 'django.db.backends.sqlite3',         'name': os.path.join(base_dir, 'db.sqlite3'),     } } 

i can't figure out error coming from.

you missing comma after django.contrib.staticfiles in installed_apps setting:

installed_apps = (     'django.contrib.admin',     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.messages',     'django.contrib.staticfiles',  # here     'polls', ) 

without comma, python interprets django.contrib.staticfiles , polls strings single one.

demo:

>>> s = ('what',  ...      'a', ...      'wonderful' ...      'world') >>> s ('what', 'a', 'wonderfulworld')  >>> s = ('what', ...      'a', ...      'wonderful', ...      'world') >>> s ('what', 'a', 'wonderful', 'world')
