Hi All,
Just launched an instance with Amazon Linux 2015.03 image, added epel-release repository and run "yum install ansible". All went fine so far.
Now when I try to run "ansible" or "ansible-playbook" from command line I get this error:
Error:
Traceback (most recent call last):
File "./ansible", line 26, in <module>
import ansible.runner
ImportError: No module named ansible.runner
I found that yum installs ansible libraries under /usr/lib64/python2.6/site-packages/ while the default python version in system (reported through "python --version") is Python 2.7.9 so it seems to be expected under /usr/lib64/python2.7/site-packages/ ... but it's not there.
$ alternatives --display python

Current `best' version is /usr/bin/python2.7.
Is this expected behaviour? Why it installs under old version of python?
Thanks in advance,

Amazon Linux already has EPEL configured, so you should just be able to do 'yum install ansible'.
It looks like you've put the EPEL repo in place for RHEL6, when Amazon Linux is closer to 7 - hence the Python 2.7 dependency.

Thanks Mark. In fact it doesn't come with "epel-release" package installed by default (amzn-ami-hvm-2015.03.0.x86_64-gp2 (ami-a10897d6)):

Yes, I run "yum install epel-release" and then "yum install ansible --enablerepo=epel" and I get this:

It seems that it picks up the 2.6 version of python as dependency and not the 2.7.9.
Note: the Amazon Linux AMI 2015.03 comes by default pre-installed with both versions.
Any idea how to sort this out?

Constantin.

Because you don't need it Constantin. Amazon Linux already has EPEL plumbed in, it's just not enabled. See...

You are right Mark. It's there.
Have you tried to run "ansible" form command line?
I still get the same error.

Oh yes. I wonder if that's something that's broken lately?
Set python2.6 to be the default alternative and it works OK...
[ec2-user@ip-172-31-34-97 ~]$ sudo alternatives --set python /usr/bin/python2.6
