Cannot install cryptography #2280

NikolaiT · 2015-08-18T13:18:04Z

Followed instructions here: http://stackoverflow.com/questions/22073516/failed-to-install-python-cryptography-package-with-pip-and-setup-py

Cannot install. This module is completely useless if not clear installation instructions are given...

cffi 1.1 does not appear to have been properly installed (possibly due to a pip issue?). Try pip install -U cffi and then installing cryptography.

NikolaiT · 2015-08-18T13:24:38Z

This worked perfectly. Huge thanks for the quick answer. But why is this not mentioned in https://cryptography.io/en/latest/installation/ ? Also: Why is the installation instructions not in the readme if it is not trivial at all? The quickstart doesn't help at all in the README if one cannot install this software so easily. Even PyCrypto can be installed better, makes me want to switch again or to switch the language as a whole because pip/setuptools is a huge pain in the ass (also the whole python3 and python2 thing)... /rant

I ran into this issue when trying to install buildout based software on Debian Jessie. The following minimal test case was enough to reproduce:

setup.py:

from setuptools import setup

setup(
    name='test',
    version='0.0.1',
    install_requires=[
        'cryptography',
    ],
)

buildout.cfg:

[buildout]
parts = test
develop = .

[test]
recipe = zc.recipe.egg
eggs = test

When trying to bin/buildout i got the following:

Develop: '/tmp/test/.'
Getting distribution for 'zc.recipe.egg>=2.0.0a3'.
Got zc.recipe.egg 2.0.3.
Installing test.
Getting distribution for 'cryptography'.

ImportError: No module named setuptools_ext
An error occurred when trying to install cryptography 1.0.2. Look above this message for any errors that were output by easy_install.
While:
  Installing test.
  Getting distribution for 'cryptography'.
Error: Couldn't install: cryptography 1.0.2

Turned out that this was caused by an old python-cffi (0.8.6) installed system wide (i.e. via the distributions package manager). apt-get --purge remove python-cffi solved the problem.

vit1251 · 2016-03-30T15:23:52Z

I have pre-installed by apt-get install "python-{package_name}" and pip does not override preinstalled version.

I make apt-get remove each of one and reinstall by pip.

@see

@see pyca/cryptography#2280

@see

Fix: 1. OS-level packages `libffi-dev` and `libssl-dev`/`openssl-dev` should be installed explicitly since Ansible 2.0.2.0(???). 2. Python package cffi should be installed explicitly since Ansible 2.0.2.0(???). 3. add '--fix-missing' for apt. @see boxcutter/ubuntu#62 @see pyca/cryptography#2280

Currently setup.sh keeps failing for me on a Debian 8 VM. Turns out the error is similar to here pyca/cryptography#2280, which is due to apt installed of cffi version being less than 1.1. Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-X8h31p-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/cryptography Storing debug log for failure in /home/nikolai/.pip/pip.log This PR also fixes #261 #267 #268 setup.sh script now installs libssl-dev #261 added cffi to requirements.txt file which fixes the error in pyca/cryptography#2280 and #268
