const fs = require("fs");
fs.rmdir("./test", { recursive: true }, (err) => {
  if (err) {
    console.error(err);
  }
});

提供递归:true选项。并且它将递归地删除给定路径下的所有文件和目录。(假设test是根目录)

从Node.js 14.14.0开始，推荐使用fs.rmSync:

fs.rmSync(dir, { recursive: true, force: true });

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);
  }
}

有一个模块叫做rimraf (https://npmjs.org/package/rimraf)。它提供了与rm -Rf相同的功能

异步用法:

var rimraf = require("rimraf");
rimraf("/some/directory", function () { console.log("done"); });

同步用法:

rimraf.sync("/some/directory");

2020年更新

从12.10.0版本开始，为选项添加了recursiveOption。

注意，递归删除是实验性的。

所以你会做同步:

fs.rmdirSync(dir, {recursive: true});

或者async:

fs.rmdir(dir, {recursive: true});

事实上的包是rimraf，但这里是我的小异步版本:

const fs = require('fs')
const path = require('path')
const Q = require('q')

function rmdir (dir) {
  return Q.nfcall(fs.access, dir, fs.constants.W_OK)
    .then(() => {
      return Q.nfcall(fs.readdir, dir)
        .then(files => files.reduce((pre, f) => pre.then(() => {
          var sub = path.join(dir, f)
          return Q.nfcall(fs.lstat, sub).then(stat => {
            if (stat.isDirectory()) return rmdir(sub)
            return Q.nfcall(fs.unlink, sub)
          })
        }), Q()))
    })
    .then(() => Q.nfcall(fs.rmdir, dir))
}
