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

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);
  }
}

其他回答

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!')
  }
}

只需使用rmdir模块!这很简单。

我修改后的答案来自@oconnecp (https://stackoverflow.com/a/25069828/3027390)

使用路径。加入可以获得更好的跨平台体验。 所以,不要忘记要求它。

var path = require('path');

也将函数重命名为rimraf;)

/**
 * Remove directory recursively
 * @param {string} dir_path
 * @see https://stackoverflow.com/a/42505874/3027390
 */
function rimraf(dir_path) {
    if (fs.existsSync(dir_path)) {
        fs.readdirSync(dir_path).forEach(function(entry) {
            var entry_path = path.join(dir_path, entry);
            if (fs.lstatSync(entry_path).isDirectory()) {
                rimraf(entry_path);
            } else {
                fs.unlinkSync(entry_path);
            }
        });
        fs.rmdirSync(dir_path);
    }
}

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);
    });
}

超速度和防故障

你可以使用lignator包(https://www.npmjs.com/package/lignator),它比任何异步代码(例如rimraf)都快,而且更防故障(特别是在Windows中,文件删除不是瞬时的,文件可能被其他进程锁定)。

4,36 GB的数据,28042个文件,4217个文件夹在Windows上在15秒内删除,而旧硬盘上的rimraf只有60秒。

const lignator = require('lignator');

lignator.remove('./build/');
