Traceback with ansible: AttributeError: 'module' object has no attribute '_vendor'

[tma...@gmail.com]

Hi all. I hope you can help me investigating the problem why my ansible installation does not want to run.

I get the following traceback in latest stable "release" as well as git checkout:

seadmin@aconf1a:/sw/ansible_gitclone/ansible/bin> ./ansible

Traceback (most recent call last):

AttributeError: 'module' object has no attribute '_vendor'

My older 2.0.0 ansible installation is running properly.

This is fixed as hacking/env-setup or python setup.py egg_info was executed.

I'm getting this error with v2.0.0-0.3.beta1 on OS X

 

[Anthony Green]

In my case the fix was to uninstall the cryptography pip I previously installed

[Srdjan Grubor]

I fixed this issue on my Ubuntu 15.10 machine by installing python-paramiko, python-selinux, and python-crypto

Try installing all dependencies from regular ansible package (apt-cache show ansible) - you might have some missing.

[Toshio Kuratomi]

If you're encountering this with the PPAs, the 2.0.0.1
python-setuptools was missing as a dependency in the debs that we
built for the PPA. That can cause this error as well. The 2.0.0.2 PPA
build should have fixed that problem.

Hello,

I had similar error:

ansible
Unexpected Exception: 'module' object has no attribute '_init_cffi_1_0_external_module'
the full traceback was:

with all dependencies for ansible installed.

It was solved after removing: sudo dnf remove python-cryptography

it solved the issue immediatelly.

looks like there are some conflicts with python-crypt and python-cryptography.

[Toshio Kuratomi]

Unfortunately, with setuptools in the mix it's just as likely that the
two python modules are compatible but when they're installed together
a setuptools bug triggers and causes things like this. setuptools
changes where python is searching for modules based on data installed
globally (all of the egginfo files of packages) so I can kind of see
how that can happen even though I can't see how this particular bug
works :-( On Ubuntu we found that even though the bug was experienced
by people with both PyCrypto and Cryptography installed the bug was
really that the setuptools egginfo wasn't installed.

In case this helps someone who finds this thread while Googling, I was able to solve this on Mac OS X by installing the cryptography package system-wide, i.e. "sudo pip install cryptography".
