Looks like it wants a newer version of cffi. What happens if you install cffi first?
I recall having some trouble getting cryptography installed when I was using Centos 6.5, but forget the details now. I think maybe I had to use yum to remove the version supplied with the OS. Things have probably moved on but my guess would be you have some conflict between the python libraries installed with the OS and the ones that are coming from pip. I would probably try uninstalling things from yum that were older versions and then having another go at the pip install (but not if the machine is doing something critical of course) Hope this helps, Jon On Friday, December 1, 2017 at 10:14:07 AM UTC, Afroz Hussain wrote: > > Hello everyone, > > I am facing an issue while installing "pywinrm" for managing my windows > host via Ansible, I am getting following errors: > > Collecting pywinrm > Using cached pywinrm-0.2.2-py2.py3-none-any.whl > Requirement already satisfied: requests>=2.9.1 in > /usr/lib/python2.6/site-packages (from pywinrm) > Requirement already satisfied: xmltodict in > /usr/lib/python2.6/site-packages (from pywinrm) > Requirement already satisfied: six in /usr/lib/python2.6/site-packages > (from pywinrm) > Collecting requests-ntlm>=0.3.0 (from pywinrm) > Using cached requests_ntlm-1.1.0-py2.py3-none-any.whl > Requirement already satisfied: chardet<3.1.0,>=3.0.2 in > /usr/lib/python2.6/site-packages (from requests>=2.9.1->pywinrm) > Requirement already satisfied: certifi>=2017.4.17 in > /usr/lib/python2.6/site-packages (from requests>=2.9.1->pywinrm) > Requirement already satisfied: urllib3<1.23,>=1.21.1 in > /usr/lib/python2.6/site-packages (from requests>=2.9.1->pywinrm) > Requirement already satisfied: idna<2.7,>=2.5 in > /usr/lib/python2.6/site-packages (from requests>=2.9.1->pywinrm) > Collecting cryptography>=1.3 (from requests-ntlm>=0.3.0->pywinrm) > Using cached cryptography-2.1.4.tar.gz > Requirement already satisfied: ntlm-auth>=1.0.2 in > /usr/lib/python2.6/site-packages (from requests-ntlm>=0.3.0->pywinrm) > Requirement already satisfied: asn1crypto>=0.21.0 in > /usr/lib/python2.6/site-packages (from > cryptography>=1.3->requests-ntlm>=0.3.0->pywinrm) > Requirement already satisfied: enum34 in /usr/lib/python2.6/site-packages > (from cryptography>=1.3->requests-ntlm>=0.3.0->pywinrm) > Requirement already satisfied: ipaddress in > /usr/lib/python2.6/site-packages (from > cryptography>=1.3->requests-ntlm>=0.3.0->pywinrm) > Collecting cffi>=1.7 (from > cryptography>=1.3->requests-ntlm>=0.3.0->pywinrm) > /usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:318: > > SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject > Name Indication) extension to TLS is not available on this platform.
