Python pip package RequestsDependencyWarning when installing elastic-search-curator

Question

I installed elastic search curator via the following command.

sudo pip install -U elasticsearch-curator

It all installed OK.

However now when I do the following

curator_cli --version

I get the following dependency warning.

 /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

How do I either fix the warning or hide it?

Answer 1

So took a couple of things for me to get this working.

First I upgraded cyptography as per Mufeeds suggestion

sudo pip install --upgrade cryptography

This then gave me a new error everytime I did pip <any command>

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 7, in <module>
    from pip._internal import main
  File "/usr/local/lib/python2.7/dist-packages/pip/_internal/__init__.py", line 42, in <module>

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

Resolved this by resintalling PyOpenSSL

sudo python -m easy_install --upgrade pyOpenSSL

Curator is now working as expected without the warnings

curator_cli --version
