title: Django cannot find an app with manage.py syncdb
body: <p>i am running Mac OS X 10.7 and I succesfully created a project in django by using
      django-admin.py startproject MyBlog. In this folder i have manage.py, another folder titled MyBlog and an app folder which i created called MainBlog.</p>
  
  <p>I needed to add this module, and a taggit module to my settings.py folder so i did (probably incorrectly).</p>
  
  <p>Here it is..</p>
  
  <pre><code>INSTALLED_APPS = (
  'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.sites',
  'django.contrib.messages',
  'django.contrib.staticfiles',
  # Uncomment the next line to enable the admin:
  'django.contrib.admin',
  'MainBlog.taggit',
  'MainBlog',
  # Uncomment the next line to enable admin documentation:
  # 'django.contrib.admindocs',
  )
  </code></pre>
  
  <p>I have also tried</p>
  
  <pre><code>'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.sites',
  'django.contrib.messages',
  'django.contrib.staticfiles',
  # Uncomment the next line to enable the admin:
  'django.contrib.admin',
  'MainBlog.taggit',
  'MyBlog.MainBlog',
  # Uncomment the next line to enable admin documentation:
  # 'django.contrib.admindocs',
  )
  </code></pre>
  
  <p>Neither of these work. They all return this error...</p>
  
  <pre><code>Error: No module named MainBlog
  </code></pre>
  
  <p>Any help would be greatly appreiciated. Ive been struggling with this for hours!</p>
