如何覆盖此 ESLint TypeScript 规则？

Question

我想覆盖@typescript/type-annotation-spacing确定:在类型注释前后放置多少空格的规则。

我想覆盖它之前和之后有一个空格:，但默认它只有一个之后。

该文档描述了此规则的几个选项，但它没有给出在eslintrc.*文件中覆盖它的完整语法的任何示例。

https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/docs/rules/type-annotation-spacing.md

This rule has an object option:

"before": false, (default for colon) disallows spaces before the colon/arrow.
"before": true, (default for arrow) requires a space before the colon/arrow.
"after": true, (default) requires a space after the colon/arrow.
"after": false, disallows spaces after the colon/arrow.
"overrides", overrides the default options for type annotations with colon (e.g. const foo: string) and function types with arrow (e.g. type Foo = () => {}).

我尝试将其添加到我的eslintrc文件中

"rules": {
        "@typescript-eslint/type-annotation-spacing": {
            before: true,
            after: true,
            severity: "warn"
        }
    }

但后来我收到了这个错误：

   Configuration for rule "@typescript-eslint/type-annotation-spacing" is invalid:
        Severity should be one of the following: 0 = off, 1 = warn, 2 = error (you passed '{ before: true, after: true, severity: "warn" }').

我尝试了其他几种变体，但它们都导致了类似的错误。

什么是正确的语法？

我查看了 ESLint 文档，它显示了将规则的多个选项放入数组中。这有效：

 "rules": {
        "@typescript-eslint/type-annotation-spacing": ["warn", {
            before: true,
            after: true
        }]
    }
