eslint – 如何知道规则在哪里“定义”

Question

给定一个项目，其节点package.json安装了 eslint 和一些插件，我怎么知道在哪里设置了特定规则？

我看到正在应用一条规则 ( space-before-function-paren)，但.eslintrc在项目的任何文件或插件文档中都找不到它。

此外，我正在使用带有一些扩展的 VSCode，例如 ESLint 本身，这可能会干扰这里，但我再次不确定如何/在哪里检查哪个部分正在应用该规则（尽管我认为这不太可能是发生，npm run lint如果代码不符合上述规则，则失败。

我正在发布 package.json 文件的相关部分：

不幸的是，似乎没有“eslint”方式来执行这样的报告。

如果使用eslint调试选项运行，您将获得有关程序如何运行的大量信息：正在处理什么文件、使用哪个配置、如何失败等，但不是从规则的获取位置获得的信息。

grep + find我通过简单地在目录中运行 a 来找到它node_modules，并通过简单地更改它并随后查看结果来确定哪个模块提供了规则eslint。
