From what I can see gixy won't run on 2.6, as it's using 2.7/3.x syntax.

If, like me, you're running CentOS 6, try installing EPEL and then python34 and python34-setuptools. You can then install using pip3.

sudo easy_install-3.4 pip
pip3 install gixy
gixy [/etc/nginx/conf.d/default.conf]

For now Gixy does not support Python 2.6 and I'm not sure if it is needed.
The last release of Python 2.6 was 2013-10-29, over 3 years ago: https://www.python.org/dev/peps/pep-0361/

For example, the pip project has recently dropped support for 2.6: pypa/pip#4343
And as I can see, CentOS 7 also used Python 2.7 by default:

$ docker run -t centos:7 python -V
Python 2.7.5

So the only popular distro with Python 2.6 is CentOS 6?

As far as I can tell, both CentOS and RHEL 6 (EL6) just support Python 2.6 (in their base repos). Then they backport security fixes back into the packages when necessary. As they're true long-term releases, EL 6 will be supported until 2020, and it still has a pretty big market share.

The only reason Gixy doesn't seem to currently work is because the set syntax is different (set([1, 2]) compared to {}) and the .format() syntax in 2.7 and 3.x.

I guess providing some brief installation instruction for CentOS 6 could be helpful as a workaround?

From the one hand, CentOS 6 ships with a Python 2.6 by default. As @Jamie0 said RHEL/CentOS 6.x will be supported until 2020 and it still has a lot of users. For example, Ansible developers support Python 2.6 as well as Python 2.7.

From the other hand, I understand that supporting compatibility with an obsolete version of Python might be painful. @buglloc I suggest you estimate how much effort and time do you need to maintain also the older version of Python interpreter. If it is not worth it, just close the issue and move on.

Supporting Python 2.6 is painful, but I'll try to support it as much as I can :)
If this becomes too difficult (in future), I'll drop it.

Fixed in Gixy v0.1.5
