謝謝善。發布您的建議作為幫助其他社區成員的答案。

您可以使用 poetry self update

如果你得到RuntimeError Poetry was not installed with the recommended installer. Cannot update automatically.這意味著你已經安裝poetry了pip

pip不支持自動詩歌更新。您應該卸載當前安裝的詩歌版本，并使用推薦的方法重新安裝它，該方法使用自定義安裝腳本。

在 osx/linux 上，您只需運行curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -下載并運行此安裝腳本。

您可以參考未使用推薦的安裝程式安裝 Poetry。無法自動更新
