python - Admin Site: TemplateDoesNotExist at /admin/

Question

I'm following Django's official Tutorial 2 but for some reason cannot create an admin site despite following all the steps correctly to my understanding.

This is the error I get:

TemplateDoesNotExist at /admin/
admin/login.html
Request Method: GET
Request URL:    http://127.0.0.1:8000/admin/
Django Version: 1.3.1
Exception Type: TemplateDoesNotExist
Exception Value:    
admin/login.html
Exception Location: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/template/loader.py in find_template, line 138

The error occurs after I uncomment the following lines (commented):

### urls.py ###
from django.conf.urls.defaults import patterns, include, url

from django.contrib import admin # THIS LINE
admin.autodiscover() # THIS LINE

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)), # THIS LINE
)

If I comment them again it gets rid of the error.

I do have django.contrib.admin in my INSTALLED_APPS in settings.py

Answer 1

I ran into the same problem, and I had to force pip to re-download django.

pip install -r requirements.txt --ignore-installed --force-reinstall --upgrade --no-cache-dir

Note: I know that the --no-cache-dir option is necessary, I'm not certain that the other options are all required.
