Python pip包在安装弹性搜索策展器时请求DependencyWarning

Question

我通过以下命令安装了弹性搜索策展器。

sudo pip install -U elasticsearch-curator

一切安装正常。

然而，现在当我做以下时

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

如何修复警告或隐藏警告？

Answer 1

所以我花了几件事才完成这项工作。

首先，我根据Mufeeds的建议升级了密码术

sudo pip install --upgrade cryptography

这给了我一个新的错误，每次我做pip <any command>

Traceback (most recent call last):
File "/usr/local/bin/pip", line 7, in <module>
from pip._internal import main

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

通过重新引入PyOpenSSL 解决了此问题

sudo python -m easy_install --upgrade pyOpenSSL

馆长现在正在按预期工作，没有的警告

curator_cli --version
> curator_cli, version 5.5.4

Answer 2

下面的第一步将更新密码学，但会破坏pyopenssl。

sudo pip install --upgrade cryptography

我们可以通过删除pyopennssl库并使用pip重新安装来解决这个问题。

sudo rm -rf /usr/lib/python2.7/dist-packages/OpenSSL
sudo rm -rf /usr/lib/python2.7/dist-packages/pyOpenSSL-0.15.1.egg-info
sudo pip install pyopenssl --upgrade
sudo pip install cryptography --upgrade

如果打开的sll库仍然被破坏，最后一行将产生错误，因此这验证了一切都应该正常。。。

我的偏好是避免另一个软件包像在混合中轻松安装一样管理，所以在其他人也喜欢的情况下共享它。
