而递归是fs.rmdir的一个实验性选项

function rm (path, cb) {
    fs.stat(path, function (err, stats) {
        if (err)
            return cb(err);

        if (stats.isFile())
            return fs.unlink(path, cb);

        fs.rmdir(path, function (err) {
            if (!err || err && err.code != 'ENOTEMPTY') 
                return cb(err);

            fs.readdir(path, function (err, files) {
                if (err)
                    return cb(err);

                let next = i => i == files.length ? 
                    rm(path, cb) : 
                    rm(path + '/' + files[i], err => err ? cb(err) : next(i + 1));

                next(0);
            });
        });
    });
}

下面是@SharpCoder的答案的异步版本

const fs = require('fs');
const path = require('path');

function deleteFile(dir, file) {
    return new Promise(function (resolve, reject) {
        var filePath = path.join(dir, file);
        fs.lstat(filePath, function (err, stats) {
            if (err) {
                return reject(err);
            }
            if (stats.isDirectory()) {
                resolve(deleteDirectory(filePath));
            } else {
                fs.unlink(filePath, function (err) {
                    if (err) {
                        return reject(err);
                    }
                    resolve();
                });
            }
        });
    });
};

function deleteDirectory(dir) {
    return new Promise(function (resolve, reject) {
        fs.access(dir, function (err) {
            if (err) {
                return reject(err);
            }
            fs.readdir(dir, function (err, files) {
                if (err) {
                    return reject(err);
                }
                Promise.all(files.map(function (file) {
                    return deleteFile(dir, file);
                })).then(function () {
                    fs.rmdir(dir, function (err) {
                        if (err) {
                            return reject(err);
                        }
                        resolve();
                    });
                }).catch(reject);
            });
        });
    });
};

return new Promise((resolve, reject) => {
  const fs = require("fs");
  // directory path
  const dir = "your/dir";

  // delete directory recursively <------
  fs.rmdir(dir, { recursive: true }, (err) => {
    if (err) {
      reject(err);
    }
    resolve(`${dir} is deleted!`);
  });
});

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);
  }
}

这是一种使用promisify和两个帮助函数(to和toAll)来解决承诺的方法。

它以异步方式执行所有操作。

const fs = require('fs');
const { promisify } = require('util');
const to = require('./to');
const toAll = require('./toAll');

const readDirAsync = promisify(fs.readdir);
const rmDirAsync = promisify(fs.rmdir);
const unlinkAsync = promisify(fs.unlink);

/**
    * @author Aécio Levy
    * @function removeDirWithFiles
    * @usage: remove dir with files
    * @param {String} path
    */
const removeDirWithFiles = async path => {
    try {
        const file = readDirAsync(path);
        const [error, files] = await to(file);
        if (error) {
            throw new Error(error)
        }
        const arrayUnlink = files.map((fileName) => {
            return unlinkAsync(`${path}/${fileName}`);
        });
        const [errorUnlink, filesUnlink] = await toAll(arrayUnlink);
        if (errorUnlink) {
            throw new Error(errorUnlink);
        }
        const deleteDir = rmDirAsync(path);
        const [errorDelete, result] = await to(deleteDir);
        if (errorDelete) {
            throw new Error(errorDelete);
        }
    } catch (err) {
        console.log(err)
    }
}; 

如果你更喜欢async/await，你可以使用fs/promises API。

const fs = require('fs/promises');

const removeDir = async (dirPath) => {
  await fs.rm(dirPath, {recursive: true});
}

如果您知道文件夹中单个文件的路径，并希望删除包含该文件的文件夹。

const fs = require('fs/promises');
const path = require('path');

const removeDir = async (filePath) => {
  const { dir } = path.parse(filePath);
  await fs.rm(dir, { recursive: true });
}
