在我的节点应用程序中,我需要删除一个目录,其中有一些文件,但fs。Rmdir只适用于空目录。我该怎么做呢?
当前回答
//不使用任何第三方lib
const fs = require('fs');
var FOLDER_PATH = "./dirname";
var files = fs.readdirSync(FOLDER_PATH);
files.forEach(element => {
fs.unlinkSync(FOLDER_PATH + "/" + element);
});
fs.rmdirSync(FOLDER_PATH);

方法删除非空目录
rmdir(path,{recursive:true,force:true}
rm(path,{recursive:true,force:true}
将工作
代码片段:
const fsp = require("fs/promises");
deleteDirRecursively("./b");
removeRecursively("./BCD/b+");
async function deleteDirRecursively(dirPath) {
try {
// fsPromises.rmdir() on a file (not a directory) results in the promise being rejected
// with an ENOENT error on Windows and an ENOTDIR error on POSIX.
// To get a behavior similar to the rm -rf Unix command,
// use fsPromises.rm() with options { recursive: true, force: true }.
//will not thorw error if dir is empty
//will thow error if dir is not present
await fsp.rmdir(dirPath, { recursive: true, force: true });
console.log(dirPath, "deleted successfully");
} catch (err) {
console.log(err);
}
async function removeRecursively(path) {
try {
//has ability to remove both file and dir
//can delete dir recursively and forcefully
//will delete an empty dir.
//will remove all the contents of a dir.
// the only difference between rmdir and rm is that rmdir can only delete dir's
await fsp.rm(path, { recursive: true, force: true });
console.log(path, "deleted successfully");
} catch (err) {
console.log(err);
}
}
❄️您可以使用graph-fs
directory.delete()
//不使用任何第三方lib
const fs = require('fs');
var FOLDER_PATH = "./dirname";
var files = fs.readdirSync(FOLDER_PATH);
files.forEach(element => {
fs.unlinkSync(FOLDER_PATH + "/" + element);
});
fs.rmdirSync(FOLDER_PATH);
从Node文档中可以看到。
要获得类似rm -rf Unix命令的行为,请使用带有选项{recursive: true, force: true}的fs.rm()。
例如(ESM)
import { rm } from 'node:fs/promises';
await rm('/path/to', { recursive: true, force: true });
另一种替代方法是使用fs-promise模块,该模块提供fs-extra模块的承诺版本
你可以这样写:
const { remove, mkdirp, writeFile, readFile } = require('fs-promise')
const { join, dirname } = require('path')
async function createAndRemove() {
const content = 'Hello World!'
const root = join(__dirname, 'foo')
const file = join(root, 'bar', 'baz', 'hello.txt')
await mkdirp(dirname(file))
await writeFile(file, content)
console.log(await readFile(file, 'utf-8'))
await remove(join(__dirname, 'foo'))
}
createAndRemove().catch(console.error)
注意:async/await需要最新的nodejs版本(7.6+)
