我的Matlab版本是R2012a
为什么Matlab 1.1-0.2不等于0.9 !!!!!？
这太可怕了!

当我运行时,python manage.py rebuild_index我收到以下错误:

Failed to clear Elasticsearch index: HTTPConnectionPool(host='127.0.0.1', port=9200): Max retries exceeded with url: /haystack (Caused by : [Errno 111] Connection refused)

My elasticsearch setting:

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

It is worth to mention that I have indexed my data once before and all things went correct but I dont know why when came back to project and restarted django project it …
