Cryptography: Cryptography installation is failing

Created on 1 Aug 2017 · 14Comments · Source: pyca/cryptography

Hi,

I am running Python version 2.6.0 on a CentOS server.

Linux version 2.6.32-431.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Sun Nov 10 22:19:54 EST 2013

I am failing to install the crypto package.

Any pointers on what could be the issue?

Also just to add I resolved the same issue by upgrading cffi to version 1.10.0. Again if you cannot use the above solutions I hope this will help

Please upgrade your pip to the latest version and try the install again. If you still get the same error we'll proceed from there :smile:

reaperhulk on 1 Aug 2017

@reaperhulk , just did. pip is now on 9.0.1. The issue exists.
Thanks

singhaniashrinkhala on 1 Aug 2017

Okay, what version of CentOS and can you supply the output of pip install -vvv cryptography (a verbose install). That will be a lot of output so you might want to put it in a gist or something.

@reaperhulk : The device doesn't have internet connectivity. Did a local install:

What version of cffi do you have installed?

alex on 2 Aug 2017

@alex cffi==1.7.0

singhaniashrinkhala on 2 Aug 2017

Can you try installing using the manylinux1 wheel from pypi?

RHEL 6.5 is pretty out of date, even within the RHEL 6 world, so it's likely this is caused by some out of date system software.

alex on 2 Aug 2017

@alex I did try that before, however I got this:

# pip install cryptography-2.0.2-cp26-cp26m-manylinux1_x86_64.whl 
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6
cryptography-2.0.2-cp26-cp26m-manylinux1_x86_64.whl is not a supported wheel on this platform.

singhaniashrinkhala on 2 Aug 2017

Chances are you need the cp26-cp26mu wheel and not the cp26-cp26m

reaperhulk on 2 Aug 2017

@reaperhulk That worked! Thank you for all the help :)

singhaniashrinkhala on 2 Aug 2017

Hi! I had the same problem and solved by upgrading pip with pip install --upgrade pip before installing cryptography. Maybe if the solution above doesn't work this could help :)
