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);
}
}

Windows的示例(没有额外的依赖和错误处理)

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

let dir = "C:\\temp\\dir1\\dir2\\dir3";

function createDirRecursively(dir) {
    if (!fs.existsSync(dir)) {        
        createDirRecursively(path.join(dir, ".."));
        fs.mkdirSync(dir);
    }
}

createDirRecursively(dir); //creates dir1\dir2\dir3 in C:\temp

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);
}

答案太多了，但这里有一个没有递归的解决方案，它通过分割路径，然后从左到右重新构建

function mkdirRecursiveSync(path) {
    let paths = path.split(path.delimiter);
    let fullPath = '';
    paths.forEach((path) => {

        if (fullPath === '') {
            fullPath = path;
        } else {
            fullPath = fullPath + '/' + path;
        }

        if (!fs.existsSync(fullPath)) {
            fs.mkdirSync(fullPath);
        }
    });
};

对于那些关心windows与Linux兼容性的人，只需将上面出现的正斜杠替换为双反斜杠'\'，但TBH，我们谈论的是节点fs而不是windows命令行，前者是相当宽容的，上面的代码将简单地工作在windows上，是一个更完整的跨平台解决方案。

下面是我为nodejs编写的mkdirp命令式版本。

function mkdirSyncP(location) {
    let normalizedPath = path.normalize(location);
    let parsedPathObj = path.parse(normalizedPath);
    let curDir = parsedPathObj.root;
    let folders = parsedPathObj.dir.split(path.sep);
    folders.push(parsedPathObj.base);
    for(let part of folders) {
        curDir = path.join(curDir, part);
        if (!fs.existsSync(curDir)) {
            fs.mkdirSync(curDir);
        }
    }
}
