Setting Your Poetry Version
Poetry is a Python packaging and dependency manager. Poetry version 1.7.1 is the default for Render Python services created on or after 2023-11-30.
Specify a different Poetry version by setting your service's POETRY_VERSION environment variable to any version number that's compatible with your Python version.
History of default Poetry versions
If you don't set a Poetry version for your service, Render's default version depends on when you originally created the service:
| Service Creation Date | Default Poetry Version |
|---|---|
2023-11-30 and later | 1.7.1 |
2021-04-27 to 2023-11-30 | 1.1.x (various) |
Before 2021-04-27 | 1.0.x (various) |
