You can get around this by installing the package in editable mode: -e. If you make changes to the library without bumping the required version number, however, the changes will not be updated at runtime. To add a local dependency in requirements.txt, specify the relative path to the directory containing setup.py. Git modules will automatically be resolved when you push your code to Heroku. You can use Git Submodules to maintain separate repositories for your File-backed dependencies. This is recommended for Git-backed distributions that rely on upstream changes, as well as larger repositories.

branch, tag, or commit) by appending an to your URL: you can install a dependency in “editable” mode, which will link to a full clone of the repository. If your package is hosted in a private Git repository, you can use HTTP Basic Authentication: can also specify any Git reference (e.g. Thanks to pip’s Git support, you can install a Python package that is hosted on a remote Git repository.įor example: git+git:///kennethreitz/requests.git

Git-backed distributionsĪnything that works with a standard pip requirements file will work as expected on Heroku. This will ensure consistent build behavior when newer package versions are released. All secondary dependencies should be explicitly specified.All package versions should be explicitly specified.If you follow these simple recommendations, your application builds will be deterministic: To specify Python package dependencies on Heroku via pip, add a pip requirements file named requirements.txt to the root of your repository. Packages with unsupported C dependencies that do not provide “manylinux” wheels will not install on Heroku. Any requirements that install locally with the following command will behave as expected on Heroku: $ pip install -r requirements.txt Heroku’s pip support is very transparent.
