在 monorepo 中使用 actions/setup-python 和詩歌緩存

Question

我正在嘗試將setup-python操作與 monorepo 一起使用，但由於在根目錄下找不到 pyproject.toml，該操作無法激活 Python 的正確版本。

Run actions/setup-python@v4
Version 3.10.0 was not found in the local cache
Version 3.10.0 is available for downloading
Download from "https://github.com/actions/python-versions/releases/download/3.10.0-117927/python-3.10.0-linux-20.04-x64.tar.gz"

      373│             )
Warning:

因此，以下步驟將失敗。 我應該如何解決這個問題？

作為 GitHub 問題，有一個開放的功能請求和解決方法。

以下片段（將實際詩歌項目的路徑存儲為環境變量FOLDER ）對我有用（本地跑步者，ubuntu 22.4）：

- name: Install Poetry
  uses: snok/install-poetry@v1
- name: Set up python
  id: setup-python
  uses: actions/setup-python@v4
  with:
    python-version: 3.9
- name: Check poetry cache
  uses: actions/cache@v3
  id: cached-poetry-dependencies
  with:
    path: ${{ env.FOLDER }}/.venv
    key: ${{ hashFiles(format('{0}/poetry.lock', env.FOLDER)) }}
- name: Install dependencies for <TOOL_IN_FOLDER>
  if: steps.cached-poetry-dependencies.outputs.cache-hit != 'true'
  run: poetry install --no-interaction --no-root
  working-directory: ${{ env.FOLDER }}

你現在可以在 GitHub 上找到這個動作
