Github Actions: poetry 安裝黑了但是CI workflow找不到

Question

我正在本地（預提交）和 Github 操作 (GHA) 上設置 python 代碼質量工作流程。 環境是用詩歌來管理的。

雖然本地預提交工作正常，但遠程 GHA 工作流失敗，說它沒有找到黑色，而在查看工作流日志時它似乎安裝得很好。 工作流程很大程度上是從這篇偉大的文章中復制的： https://jacobian.org/til/github-actions-poetry/

我在哪里犯了錯誤？ 以下是相關文件：

    # Cache the installation of Poetry itself, e.g. the next step. This prevents the workflow
    # from installing Poetry every time, which can be slow. Note the use of the Poetry version
    # number in the cache key, and the "-0" suffix: this allows you to invalidate the cache
    # manually if/when you want to upgrade Poetry, or if something goes wrong. This could be
    # mildly cleaner by using an environment variable, but I don't really care.
    - name: cache poetry install

    # Install Poetry. You could do this manually, or there are several actions that do this.
    # `snok/install-poetry` seems to be minimal yet complete, and really just calls out to
    # Poetry's default install script, which feels correct. I pin the Poetry version here
    # because Poetry does occasionally change APIs between versions and I don't want my
    # actions to break if it does.
    #
    # The key configuration value here is `virtualenvs-in-project: true`: this creates the
    # venv as a `.venv` in your testing directory, which allows the next step to easily
    # cache it.

    # Cache your dependencies (i.e. all the stuff in your `pyproject.toml`). Note the cache

    # Install dependencies. `--no-root` means "install all dependencies but not the project
    # itself", which is what you want to avoid caching _your_ code. The `if` statement
    # ensures this only runs on a cache miss.
    - run: poetry install --no-interaction --no-root
      if: steps.cache-deps.outputs.cache-hit != 'true'

    # Now install _your_ project. This isn't necessary for many types of projects -- particularly
    # things like Django apps don't need this. But it's a good idea since it fully-exercises the
    # pyproject.toml and makes that if you add things like console-scripts at some point that
    # they'll be installed and working.

由於依賴安裝在Poetry管理的虛擬環境中，所以需要使用Poetry來run Black：

- name: Format with black
  run: poetry run black 'src'
