cibuildwheel auto-deploy to PyPI example

Travis setup

• Add an env section to your .travis.yml

  env:
    global:
      - TWINE_USERNAME=...your pypi username...
      # Note: TWINE_PASSWORD is set in Travis settings
  

  And add an upload step to the script section

  script:
    - pip install cibuildwheel==x.x.x
    - cibuildwheel --output-dir wheelhouse
    - |
      if [[ $TRAVIS_TAG ]]; then
        python -m pip install twine
        python -m twine upload wheelhouse/*.whl
      fi
  

  Check this repo's .travis.yml as an example.

• In the Travis web UI, go to your project settings and add the environment variable TWINE_PASSWORD, set to your PyPI password.

Appveyor setup

• Add this env to your appveyor.yml

  environment:
    TWINE_USERNAME: ...your pypi username...
    # Note: TWINE_PASSWORD is set in Appveyor settings
  

  Add this upload step to the build_script:

  build_script:
    - pip install cibuildwheel==x.x.x
    - cibuildwheel --output-dir wheelhouse
    - >
      IF "%APPVEYOR_REPO_TAG%" == "true"
      (
      python -m pip install twine
      &&
      python -m twine upload wheelhouse/*.whl
      )
  

  Check this repo's appveyor.yml as an example.

• In the Appveyor UI, add your PyPI password as TWINE_PASSWORD (click Settings > Environment > Add Variable...). Make sure to mark it as private!

On each release

• Bump the version number in setup.py and anywhere else it occurs (I use bumpversion for this)
• Commit these changes, tag that commit, and push to Github (don't forget to push the tag! git push --tags). Your wheels will start building.
• Locally, build a source distribution with rm -rf dist && python setup.py sdist
• Upload the source distribution using twine upload dist/*.tar.gz

Your wheels will build in Travis/Appveyor and push to PyPI when ready.
