安装 eslint 预提交钩子错误

Question

我正在尝试安装 eslint 预提交挂钩 (https://github.com/pre-commit/mirrors-eslint)

这是我的预提交文件中的条目：

-   repo: https://github.com/pre-commit/mirrors-eslint
    rev: 'v7.4.0'
    hooks:
    -   id: eslint

但是，当我运行预提交时，我得到以下信息：

[INFO] Initializing environment for https://github.com/pre-commit/mirrors-eslint.
[INFO] Initializing environment for https://github.com/pre-commit/mirrors-eslint:eslint@7.4.0.

Check the log at C:\Users\username/.cache\pre-commit\pre-commit.log

我不明白那个文件是什么或者为什么 eslint 需要它。 当我直接从终端使用 Eslint 时，它可以工作，这确认它是作为独立安装的，并且也可以按预期工作。

您应该能够在不预先提交的情况下重现此崩溃，只需使用 nodeenv -- 尝试以下操作：

nodeenv nenv --prebuilt --clean-src

---

我认为这是可能的唯一方法是，如果您有一个 nodeenv 配置文件，其中包含 with_npm = true 和 npm = ...（一些非常旧的 npm 版本，它不提供 npm.cmd 文件）

您可以尝试从您的配置文件中删除这些内容吗？我相信它可以在以下任何地方：

• ./tox.ini
• ./setup.cfg
• %HOMEPATH%/.nodeenvrc
