Travis CI can automatically release your Python package to PyPI after a successful build.
For a minimal configuration, add the following to your
deploy: provider: pypi user: "Your username" password: "Your password"
However, this would expose your PyPI password to the world. We recommend you encrypt your password using the Travis CI command line client:
travis encrypt your-password-here --add deploy.password
Note that if your PyPI password contains special characters you need to escape them before encrypting your password. Some people have reported difficulties connecting to PyPI with passwords containing anything except alphanumeric characters.
deploy: provider: pypi user: "Your username" password: secure: "Your encrypted password"
Deploying tags #
Most likely, you would only want to deploy to PyPI when a new version of your package is cut. To do this, you can tell Travis CI to only deploy on tagged commits, like so:
deploy: provider: pypi user: ... password: ... on: tags: true
If you tag a commit locally, remember to run
git push --tags to ensure that your tags are uploaded to GitHub.
Deploying specific branches #
You can explicitly specify the branch to release from with the on option:
deploy: provider: pypi user: ... password: ... on: branch: production
Alternatively, you can also configure Travis CI to release from all branches:
deploy: provider: pypi user: ... password: ... on: all_branches: true
By default, Travis CI will only release from the master branch.
Builds triggered from Pull Requests will never trigger a release.
Releasing to a self hosted PyPI #
To release to a different PyPI index:
deploy: provider: pypi user: ... password: ... server: https://mypackageindex.com/index
Uploading different distributions #
By default, only a source distribution (‘sdist’) will be uploaded to PyPI.
If you would like to upload different distributions, specify them using the
distributions option, like this:
deploy: provider: pypi user: ... password: ... distributions: "sdist bdist_wheel" # Your distributions here
If you specify
bdist_wheel in the distributions, the
wheel package will automatically be installed.
Upload artifacts only once #
By default, Travis CI runs the deploy stage for each
environment that you specify. Many of these will generate competing build artifacts that will fail to upload to pypi with a message something like this:
HTTPError: 400 Client Error: File already exists. See https://pypi.org/help/#file-name-reuse for url: https://upload.pypi.org/legacy/
To avoid this, use the
deploy: provider: pypi user: ... password: ... skip_existing: true
Releasing build artifacts #
After your tests ran and before the release, Travis CI will clean up any additional files and changes you made.
Maybe that is not what you want, as you might generate some artifacts that are supposed to be released, too. There is now an option to skip the clean up:
deploy: provider: pypi user: ... password: ... skip_cleanup: true
Conditional releases #
You can deploy only when certain conditions are met.
See Conditional Releases with
Running commands before and after release #
Sometimes you want to run commands before or after releasing a package. You can use the
after_deploy stages for this. These will only be triggered if Travis CI is actually pushing a release.
before_deploy: "echo 'ready?'" deploy: .. after_deploy: - ./after_deploy_1.sh - ./after_deploy_2.sh
