Python pip包安装elastic-search-curator时出现RequestsDependencyWarning

我通过以下命令安装了弹性搜索策展人。

sudo pip install -U elasticsearch-curator

一切都安装好了。

但是现在当我执行以下操作时

curator_cli --version

我收到以下依赖性警告。

 /usr/local/lib/python2.7/dist-packages/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)
curator_cli, version 5.5.4

如何修复或隐藏警告？

所以我做了一些事情才能让它发挥作用。

首先，我按照 Mufeeds 的建议升级加密技术

sudo pip install --upgrade cryptography

然后每次我这样做都会给我一个新的错误pip <any command>

    SSL_ST_INIT = _lib.SSL_ST_INIT
AttributeError: 'module' object has no attribute 'SSL_ST_INIT'

通过重新安装 PyOpenSSL 解决了这个问题

sudo python -m easy_install --upgrade pyOpenSSL

Curator 现在正在按预期工作，没有警告

curator_cli --version
> curator_cli, version 5.5.4
