i cannot run the TracChildTickets 2.5.2 plugin. In the Trac logs i can see:

Skipping "Tracchildtickets 2.5.2": ("DistributionNotFound: Python>=2.4" not found)

Replying to anonymous:

i am using Trac 0.12.4, Python 2.5.4 and build the plugin from the 0.12 branch (Tracchildtickets-2.5.2-py2.5)

What version of setuptools do you have installed?

Take a look at #7017 and #9589.

Putting an install_requires for Python causes problems, as noted in other tickets. Just delete the line from and it should install fine.

Best match is not Python 3.3, but Python 2.5

That demonstrates the problem with including Python as a dependency in install_requires. Would you really want the installation of a plugin to result in the download and installation of Python?

A different approach is to check whether the Python interpreter that you are executing from meets a requirement, and if not then issue an error. [13472] is an example of that approach.
