这个版本在Windows上比上面的答案工作得更好，因为它同时理解/和路径。sep，以便向前斜杠在Windows上工作，因为他们应该。支持绝对路径和相对路径(相对于process.cwd)。

/**
 * Creates a folder and if necessary, parent folders also. Returns true
 * if any folders were created. Understands both '/' and path.sep as 
 * path separators. Doesn't try to create folders that already exist,
 * which could cause a permissions error. Gracefully handles the race 
 * condition if two processes are creating a folder. Throws on error.
 * @param targetDir Name of folder to create
 */
export function mkdirSyncRecursive(targetDir) {
  if (!fs.existsSync(targetDir)) {
    for (var i = targetDir.length-2; i >= 0; i--) {
      if (targetDir.charAt(i) == '/' || targetDir.charAt(i) == path.sep) {
        mkdirSyncRecursive(targetDir.slice(0, i));
        break;
      }
    }
    try {
      fs.mkdirSync(targetDir);
      return true;
    } catch (err) {
      if (err.code !== 'EEXIST') throw err;
    }
  }
  return false;
}

现在NodeJS >= 10.12.0，你可以使用fs。mkdirSync(path， {recursive: true}

递归创建目录的异步方法:

import fs from 'fs'

const mkdirRecursive = function(path, callback) {
  let controlledPaths = []
  let paths = path.split(
    '/' // Put each path in an array
  ).filter(
    p => p != '.' // Skip root path indicator (.)
  ).reduce((memo, item) => {
    // Previous item prepended to each item so we preserve realpaths
    const prevItem = memo.length > 0 ? memo.join('/').replace(/\.\//g, '')+'/' : ''
    controlledPaths.push('./'+prevItem+item)
    return [...memo, './'+prevItem+item]
  }, []).map(dir => {
    fs.mkdir(dir, err => {
      if (err && err.code != 'EEXIST') throw err
      // Delete created directory (or skipped) from controlledPath
      controlledPaths.splice(controlledPaths.indexOf(dir), 1)
      if (controlledPaths.length === 0) {
        return callback()
      }
    })
  })
}

// Usage
mkdirRecursive('./photos/recent', () => {
  console.log('Directories created succesfully!')
})

找不到创建具有所需权限的目录的示例。

使用您想要的权限以异步递归方式创建目录。

下面是一个简单的nodejs解决方案

节点v18.12.1 Ubuntu 18

//-----------------------------
const fs = require('fs');
const fsPromises = fs.promises;
const checkDirAccess = async (userDir) => {
    try {
      await fsPromises.access(userDir, fs.constants.R_OK | fs.constants.W_OK);
      console.log(` ${userDir} Dir existss`);
      return userDir;
    } catch (err) {
        if(err.errno = -2)
            return await crDir(userDir);
        else
            throw err;
    }
}
const crDir = async (userDir) => {
    try {
      let newDir = await fsPromises.mkdir(userDir, { recursive: true, mode: 0o700}); 
      // When userDir is created; newDir = undefined;
      console.log(` Created new Dir ${newDir}`);
      return newDir;
    } catch (err) {
      throw err;
    }
}
const directoryPath =  ['uploads/xvc/xvc/xvc/specs', 'uploads/testDir11', 'uploads/xsXa/', 'uploads//xsb//', 'uploads//xsV/'];

const findDir = async() => {
try {
    for (const iterator of directoryPath) {
        let dirOK = await checkDirAccess(iterator);
        if(dirOK)
           console.log(`found ${dirOK}`)        
    }
    
} catch (error) {
    console.error('Error : ', error);
}
}

基于mouneer的零依赖回答，这里有一个初学者更友好的Typescript变体，作为一个模块:

import * as fs from 'fs';
import * as path from 'path';

/**
* Recursively creates directories until `targetDir` is valid.
* @param targetDir target directory path to be created recursively.
* @param isRelative is the provided `targetDir` a relative path?
*/
export function mkdirRecursiveSync(targetDir: string, isRelative = false) {
    const sep = path.sep;
    const initDir = path.isAbsolute(targetDir) ? sep : '';
    const baseDir = isRelative ? __dirname : '.';

    targetDir.split(sep).reduce((prevDirPath, dirToCreate) => {
        const curDirPathToCreate = path.resolve(baseDir, prevDirPath, dirToCreate);
        try {
            fs.mkdirSync(curDirPathToCreate);
        } catch (err) {
            if (err.code !== 'EEXIST') {
                throw err;
            }
            // caught EEXIST error if curDirPathToCreate already existed (not a problem for us).
        }

        return curDirPathToCreate; // becomes prevDirPath on next call to reduce
    }, initDir);
}

你可以简单地检查文件夹存在或不递归的路径，并使文件夹，因为你检查，如果他们不存在。(没有外部库)

function checkAndCreateDestinationPath (fileDestination) {
    const dirPath = fileDestination.split('/');
    dirPath.forEach((element, index) => {
        if(!fs.existsSync(dirPath.slice(0, index + 1).join('/'))){
            fs.mkdirSync(dirPath.slice(0, index + 1).join('/')); 
        }
    });
}
