Windows + PyPI is still broken.

Original issue #955 was closed by a bot, but the issue still hasn't been fixed! Repeated here:

---

I've recently tried deployment using Travis and Windows. The error I get when installing deployment requirements:

$ ruby -S gem install dpl
Successfully installed dpl-pypi-1.10.7
Parsing documentation for dpl-pypi-1.10.7
Installing ri documentation for dpl-pypi-1.10.7
Done installing documentation for dpl-pypi after 0 seconds
1 gem installed
Installing deploy dependencies
failed to deploy
-z was unexpected at this time.
Couldn't install pip, setuptools, twine or wheel.

It seems like it tries to use cmd instead of bash. I've dig into the source code and found this so I think that -z comes from this line. I don't know if it is enough to just prefix this command with bash -c. What I am afraid of here is that Windows uses git bash for its build scripts and cmd is used here so I am not sure whether virtual environment would be even preserved here.

If someone comes across this:

You can do a manual deploy via a script instead. This is what worked for my use case, not everything might be necessary for a minimal setup though! You might want to fine-tune the script for your use case.

file .travis.yml:

os: windows
language: sh

install: choco install python --version 3.6.8
env: PATH=/c/Python36:/c/Python36/Scripts:$PATH
script: python --version

deploy:
  skip_cleanup: true
  provider: script
  script: bash ./.travis/deploy.sh

file .travis/deploy.sh:

pip install twine wheel
python ./setup.py sdist bdist_wheel
twine upload \
    --username "************" \
    --password "************" \
    ./dist/*

Installing python3 takes quite some time, but I couldn't get it to work out of the box with the pre-installed python2 and I needed a python 3.6 wheel anyways.

Has it been resolved? I still see -z in the code but it might have been resolved elsewhere.
