//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);

const fs = require("fs")
const path = require("path")

let _dirloc = '<path_do_the_directory>'

if (fs.existsSync(_dirloc)) {
  fs.readdir(path, (err, files) => {
    if (!err) {
      for (let file of files) {
        // Delete each file
        fs.unlinkSync(path.join(_dirloc, file))
      }
    }
  })
  // After the 'done' of each file delete,
  // Delete the directory itself.
  if (fs.unlinkSync(_dirloc)) {
    console.log('Directory has been deleted!')
  }
}

一种快速而肮脏的方法(可能用于测试)可能是直接使用exec或spawn方法调用OS调用来删除目录。阅读更多NodeJs child_process。

let exec = require('child_process').exec
exec('rm -Rf /tmp/*.zip', callback)

缺点是:

你依赖于底层的操作系统，即相同的方法可以在unix/linux中运行，但可能不能在windows中运行。 您不能根据条件或错误劫持流程。您只需将任务交给底层操作系统，并等待退出码返回。

好处:

这些流程可以异步运行。 可以监听命令的输出/错误，因此命令输出不会丢失。如果操作未完成，请检查错误码后重试。

❄️您可以使用graph-fs

directory.delete()

我希望有一种方法可以做到这一点，而不需要为如此微小和常见的东西添加额外的模块，但这是我能想到的最好的方法。

更新: 现在应该在Windows上工作(测试Windows 10)，也应该在Linux/Unix/BSD/Mac系统上工作。

const
    execSync = require("child_process").execSync,
    fs = require("fs"),
    os = require("os");

let removeDirCmd, theDir;

removeDirCmd = os.platform() === 'win32' ? "rmdir /s /q " : "rm -rf ";

theDir = __dirname + "/../web-ui/css/";

// WARNING: Do not specify a single file as the windows rmdir command will error.
if (fs.existsSync(theDir)) {
    console.log(' removing the ' + theDir + ' directory.');
    execSync(removeDirCmd + '"' + theDir + '"', function (err) {
        console.log(err);
    });
}

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);
  }
}
