错误:'elasticsearch'后端需要安装'requests'.我如何解决它？

Question

当我在haystack和elasticsearch支持的应用程序中运行"python manage.py rebuild_index"时出现问题.

Python 2.7 Django版本1.6.2 Haystack 2.1.0 Elasticsearch 1.0

请查看出现的错误:

我已经安装了运行这些应用程序所需的所有软件包,但询问请求是什么,它是什么？

Answer 1

做就是了

pip install pyelasticsearch

Answer 2

如果您只是通过 pip 安装requests模块，此错误应该会消失。
