ESModule

__dirname

es模块中无__dirname 全局变量，只能通过 import.meta 获取文件名称，再通过 path.dirname 获取

import * as path from "path";
import { fileURLToPath } from "url";
const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);
console.log(__dirname);
console.log(path.resolve(__dirname, ".."));
