Can't get Elasticsearch working with Django

I'm trying to use Django and Haystack with Elasticsearch as the backend on Ubuntu 14.04. I have Elasticsearch and Haystack installed.

The error I receive when I run python manage.py runserver:

me@ubuntu:$ python manage.py runserver
Validating models...

Django version 1.5.4, using settings 'website_project.settings'

Quit the server with CONTROL-C.

MissingDependency: The 'elasticsearch' backend requires the installation of 'elasticsearch'. Please refer to the documentation.

My PYTHONPATH is

home/me/.pythonbrew/pythons/Python-2.7.5/lib:/usr/local/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages

I have 'haystack' in my list of INSTALLED_APPS and have the following config:

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
        'URL': 'http://127.0.0.1:9200/',
        'INDEX_NAME': 'haystack',
    },
}

I can start Elasticsearch with

sudo service elasticsearch start

and when I go to http://localhost:9200/ I see 

 {
  "status" : 200,
  "name" : "Stranger",
  "version" : {
    "number" : "1.1.1",
    "build_hash" : "somehash",
    "build_timestamp" : "2014-04-16T14:27:12Z",
    "build_snapshot" : false,
    "lucene_version" : "4.7"
  },
  "tagline" : "You Know, for Search"
}

It seems like I have Elasticsearch installed so I don't know why I am getting the 

 MissingDependency: The 'elasticsearch' backend requires the installation of 'elasticsearch'. Please refer to the documentation.

error.

Seems you've already fixed it, but for future Googlers: some people have trouble with the Haystack versions on pip around 2014-2015. Fixing the version at 2.1.0 seems to fix it, as does downloading 2.4.0 directly from git:

pip install git+https://github.com/django-haystack/django-haystack

UPDATE: The current version of haystack in pypi works (nov 2015), be sure to update!
