CodePudding user response：

Thank you Seon. Posting your suggestion as an answer to help other community members.

You can use poetry self update

If you get RuntimeError Poetry was not installed with the recommended installer. Cannot update automatically. which means you have installed poetrywith pip

pip does not support automatic poetry updates. You should uninstall the poetry version currently installed, and reinstall it using the recommended method, which uses a custom installation script.

On osx/linux, you'll just have to run curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python - to downlaod and run this installation script.

You can refer to Poetry was not installed with the recommended installer. Cannot update automatically
