I need to run tests against all (supported) versions of Python, i.e. 2.7, 3.4 through 3.7, PyPy and PyPy3. I do a matrix build (python: …, os: …) and I’d need at least
pip installed, so that I can install ideally
tox-travis and run
pyclean PR #6 shows my attempt. The resulting stages look good, now only Python support is missing!
