描述

¥Description

禁止在全局作用域中使用 __dirname 和 __filename。

¥Disallow the use of __dirname and __filename in the global scope.

它们是在 ES 模块中不可用。从 Node.js 20.11 开始，ES 模块中引入了 import.meta.dirname 和 import.meta.filename，其功能与 CommonJS (CJS) 中的 __dirname 和 __filename 完全相同。

¥They are not available in ES modules. Starting with Node.js 20.11, import.meta.dirname and import.meta.filename have been introduced in ES modules, providing identical functionality to __dirname and __filename in CommonJS (CJS).
