The exact same test with exact same configuration is OK with Ansible 2.5.0 (instead of 2.5.1).

[retr0h]

@StephenSorriaux what version of testinfra are you using?

[StephenSorriaux]

@retr0h I am using testinfra 1.7.1 in both cases

[saez0pub]

Hello,

The same for me.
we have an incompatibility since last update. The same rror occurs

I'm having the same problem here.
My "workaround" was to downgrade ansible to version 2.5.0 instead of using 2.5.1.

Everything is working again using the following versions:

• ansible==2.5.0
• molecule==2.12.1
• pytest==3.5.0
• testinfra==1.7.1

[StephenSorriaux]

Yes, I'm currently doing the same thing.

[anaelChardan]

Sorry for the question, but how do you downgrade to Ansible 2.5.0, it seems that it has been removed from apt?

Thanks ;)

[retr0h]

I personally wouldn't mix apt python packages with pip python packages. If you're using Molecule, I suggest going full out on virtualenv and simply install the dependencies with pip. The quickstart should get you going.

[jgeusebroek]

Actually I'm still having this issue.

Am I missing something?

[retr0h]

You're using testinfra 1.7.1 and it was fixed in testinfra 1.12.0.

[jgeusebroek]

Thanks, I noticed that, but shouldn't the latest testinfra be installed with a _pip install molecule_?

Collecting testinfra==1.7.1 (from molecule) Using cached https://files.pythonhosted.org/packages/49/1c/3c276b76417553143b1976719c9c7d37a0a6e3d26451dee55177a8098d5a/testinfra-1.7.1-py2.py3-none-any.whl

When installing molecule on a 'clean' machine it also installs 1.7.1. (log)

[retr0h]

Thats because Molecule 2.13 has not been released yet, which includes this fix.

[jgeusebroek]

That explains it. My bad. I'll just have to wait for release, thanks.
