Problem

Following error is happening on some Python 2.7 builds on Travis now:

Cause

Regression in Pytest 3.3.0. See:

Pytest 3.3.1 fixes the issue, but for some reason Travis is still picking up v3.3.0 from time to time.

Fix

Change pytest requirement from:

'pytest>=2.8.0',

to:

'pytest>=2.8.0,!=3.3.0',
