您好，我試圖了解以下代碼中發(fā)生的情況：import fs from "fs";import util from "util";import split2 from "split2";async function main() {    const files = await fs.promises.readdir("..");    for (const f of files) {        const s = fs.createReadStream("../" + f);        const ss = s.pipe(split2());        s.on("error", (err) => {            console.log(err);        });        for await (const l of ss) {        }        console.log(f);    }    console.log("Returning");    return "Done";}main();它基本上讀取目錄中的每個文件并迭代每個文件的行（通過使用 forawait 語法將可讀流通過管道輸送到 split2 庫中。問題是，當文件確實是目錄時，createReadStream 失?。S后什么也沒有發(fā)生）奇怪的是，似乎一個錯誤導致主函數(shù)默默退出并在錯誤之前僅顯示幾個文件名。.gitignoreapp.js[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}如果我只是評論await for 循環(huán)，我會得到以下輸出。.gitignoreapp.jsbusinesscomponentsconfigenv.skeletronnode_modulespackage-lock.jsonReturning[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}[Error: EISDIR: illegal operation on a directory, read] {  errno: -21,  code: 'EISDIR',  syscall: 'read'}  這確實是完整的文件列表，并且各個錯誤不會停止外循環(huán)。我在 Ubuntu 機器上使用節(jié)點 v14.0.0 運行它。知道發(fā)生了什么事嗎？我真的迷路了:-D
