Compose: syntaxerror with Python 2.6

[jeffallen]

I have docker-compose installed in a venv with Python26 (required for the product I am working on).

I get this:

(venv) jra@donut:~/unifield/automafield/testfield$ docker-compose port uf-server 8069
Traceback (most recent call last):
File "/home/jra/venv/bin/docker-compose", line 7, in

from ..bundle import get_image_digests

SyntaxError: invalid syntax

This is the first of many syntax errors in bundle.py.

Hi!

Unfortunately Compose does not support Python 2.6 - it is too ancient to justify the effort at that point. You can still use the binary version regardless of your Python environment however.

I understand, but then it needs to be better documented. If there is a feature of setup.py to prevent install on 2.6 that would also help.
