eslint

Question

给定一个项目，其节点 package.json 安装了 eslint 和一些插件，我如何知道特定规则的设置位置？

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

此外，我正在使用 VSCode 进行一些扩展，例如 ESLint 本身，这可能会干扰此处，但我再次不确定 how/where 来检查哪个部分正在应用该规则（尽管我认为这不太可能发生，因为如果代码不符合上述规则，npm run lint 就会失败。

我正在发布 package.json 文件的相关部分：

不幸的是，似乎没有“eslint”方式来执行此类报告。

如果你运行 eslint 使用调试选项，你会得到很多关于程序如何运行的信息：正在处理什么文件，使用哪种配置，它是如何失败的等，但不是从哪里采纳了规则。

我设法通过在 node_modules 目录中运行宁一个 grep + find 找到它，并通过简单地更改它并查看 [= =10=] 之后的结果。
