Dear All,

I’m unable to install ansible via pip on Centos 5.10:

Usually I have some idea on what to investigate next, but in this case. I’m stumped…

Hrm yes, that seems to be broken because of a dependency issue. You can try and install a slightly older version of the ecdsa library first, to see if that gets you around the issue?

The more correct answer here is Ansible on the control machine requires python 2.6 or higher.

The remote machines only need python 2.4 or higher.

Mark,

Were you able to install ansible? I am seeing the same error message and my python version is 2.7.2. I am installing on CentOS 5.6.

Ansible does _NOT_ support running on CentOS 5.X as a control machine.

It will manage them as guests.

I would highly recommend installing on 6.X, a Fedora, Ubuntu, or a Mac, as good/easy alternatives.

The reason for this is python 2.6 is on the control machine - you can do this if you know what you are doing, but we can’t really spend too much time helping with it, especially when problems are reported.
