Upgrading pip version to master branch in github before tox install dependencies

Question

I want to upgrade my pip version to pip 10.0.0.dev0 with master pip version in github like pip install -I https://github.com/pypa/pip/archive/master.zip#egg=pip before tox installs the dependencies. Is there a way to this?

My current tox file is like below

[tox]
envlist = py36

[testenv]
passenv = *
deps=
  -rrequirements.txt
commands=
  pip --version
  pytest tests

Answer 1

I think the way to upgrade pip before installing dependencies is to stop using deps and run everything in commands :

[testenv]
commands=
  pip install -I https://github.com/pypa/pip/archive/master.zip#egg=pip
  pip install -rrequirements.txt
  pytest tests
