ESLint：eslintrc 中的意外属性 "indent"

Question

如文档所述here，有一个名为 indent 的用于缩进的 ESLint 属性。该示例如下所示：

Or for tabbed indentation:
{
    "indent": ["error", "tab"]
}

但是，如果我将这段确切的代码粘贴到我的 .eslintrc 文件中，VS Code 会将其显示为错误：

ESLint: ESLint configuration in .eslintrc is invalid: - Unexpected top-level property "indent". . Please see the 'ESLint' output channel for details.

我之前的.eslintrc文件已经有很多规则，并且没有打印出错误。如果我将 "indent" 添加到该列表，或者单独添加，它会失败。

这是在 VS Code 的 ESLint 输出通道中打印的错误和堆栈跟踪：

[Error - 10:38:55 PM] ESLint stack trace:
[Error - 10:38:55 PM] Error: ESLint configuration in .eslintrc is invalid:

这是怎么回事？这个选项不知何故无效吗？示例配置错误吗？我的 ESLint extension 有问题吗？ VS Code 有问题吗？我正在使用 Ubuntu 18.04 Linux 64 位 VS Code 1.40.1，ESLint 扩展 1.9.1，eslint --version 是 v5.16.0.

不允许将此设置放在顶层属性，这意味着它必须嵌套在另一个属性，即"rules"。所以你必须这样写：

{
    //... other stuff ...

    "rules": {
        "indent": [ "error", "tab" ]
    }
}
