我正在尝试通过使用以下设置在预提交时使用黑色：

repos:
-   repo: https://github.com/ambv/black
    rev: stable
    hooks:
    - id: black
      language_version: python3.7

不幸的是，我收到了这个错误：（如果我尝试使用 python3.6 格式化，它不会发生，但我真的需要 3.7！）

错误消息表明您的机器上没有安装 python3.7 - 您需要安装它才能使用language_version: python3.7

也许您打算改用布莱克的--target论点？

    -   id: black
        # or configure black in pyproject.toml (probably a better suggestion)
        args: [--target-version, py37]
