[TIP] Problems running tox on Jenkins

[Adrian Petrescu]

Hey guys,

I have a fairly simple 3-module python project that I'm testing
successfully using Tox, on Python 2.6 and 2.7. The tox configuration is
almost completely vanilla, nothing special there. Everything works fine
when I run tox directly on my OS X development machine.

However, things go wrong when trying to run this on my Jenkins server
(running Ubuntu 12.04). I have tried to set up Tox to run both directly
through the Python plugin for Jenkins (where I invoke Tox directly from a
Python script using tox.cmdline()) as well as through the ShiningPanda
plugin. In both cases, and for both Python 2.6 and 2.7, I get the following
error:

The baffling part is that *running tox directly on the Linux box, even as
the jenkins user, works just fine!* This issue *only* shows up when run
through Jenkins, but in that case it shows up no matter how I invoke it
(ShiningPanda, Python, etc.).

I feel I must have a simple misconfiguration here, but the stack trace is
completely opaque to me. Does anyone have any insight they can provide?

Thanks!
