I’m running an open source project called gocd-cli which is, well, a command line interface for Go continuous delivery. The intention is to make it easier to handle common tasks around Go. But this post isn’t really about that.
This project is supposed to be as portable as I can make it, becuse the original need I felt for it was born on RHEL6. Which is blessed with Python 2.6 by default. And we should definitely be looking to the future, meaning supporting Python 3, and I luckily got a pull request for just that. Since I couldn’t find any free hosted Go around I went for the next best thing, Snap CI, which is also built by ThoughtWorks.
Snap supports all the versions of Python that I want by default, but they weren’t all being made available at the same time. Python 2.6 and 2.7 were always there, but only one version of Python 3 at a time.

$PATH, and tox ran

And look, my tests are passing!
