Cryptography: pip install fails on dependencies

[stefanfoulis]

Tested with _python 2.7.8_ (brew) on _OSX 10.10.4_ and pip==1.5.6.

pip install cryptography on a fresh virtualenv fails if all the dependencies have not been manually installed in beforehand:

Manually running pip install cffi will allow cryptography to go a step further, but will also fail on ipaddress, enum34, six, idna and pycparser.

It seems to work on ubuntu 14.04 with pip==1.5.6 and pip==6.1.1 though. So I'm not entirely sure this is a cryptography issue.

What version of setuptools is in your venv? (Paging @dstufft)

[alex]

No feedback here, closing for now. Will reopen if there's more info.

[jjuu]

The same issue, virtualenv version is 1.11.6.

[electronicsguy]

@alex @reaperhulk Same issue on my Raspberry Pi running Debian Wheezy (linux kernel v4.1.19), python 2.7, setuptools version 28.2.0. If I install the packages mentioned above manually, cryptography finally installs like a charm.

[junna-zhou]

the same error.....
I tried to install libffi-devel once again, then it successed.
$yum install libffi-devel

[brettdh]

Wow - I updated virtualenv (1.11.6 -> 15.0.3) and this problem went away. 🙌

[FANGXIANGQUAN]

I solved this problem after I installed cffi.
pip install cffi
Successfully installed cffi-1.11.4 pycparser-2.18
Successfully installed ansible-2.4.2.0 cryptography-2.1.4
