Services created before 2025-06-12 have a different default version. See below. |
Poetry is a packaging and dependency manager for Python. It's automatically included in Render's native Python runtime.
To specify a Poetry version, set your service's POETRY_VERSION environment variable to any version number that's compatible with your Python version.
