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);
}

更新

NodeJS 10.12.0版本增加了对mkdir和mkdirSync的本地支持，使用recursive: true选项递归地创建目录，如下所示:

fs.mkdirSync(targetDir, { recursive: true });

如果你喜欢fs Promises API，你可以写

fs.promises.mkdir(targetDir, { recursive: true });

原来的答案

如果目录不存在，则递归地创建目录!(零依赖关系)

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

function mkDirByPathSync(targetDir, { isRelativeToScript = false } = {}) {
  const sep = path.sep;
  const initDir = path.isAbsolute(targetDir) ? sep : '';
  const baseDir = isRelativeToScript ? __dirname : '.';

  return targetDir.split(sep).reduce((parentDir, childDir) => {
    const curDir = path.resolve(baseDir, parentDir, childDir);
    try {
      fs.mkdirSync(curDir);
    } catch (err) {
      if (err.code === 'EEXIST') { // curDir already exists!
        return curDir;
      }

      // To avoid `EISDIR` error on Mac and `EACCES`-->`ENOENT` and `EPERM` on Windows.
      if (err.code === 'ENOENT') { // Throw the original parentDir error on curDir `ENOENT` failure.
        throw new Error(`EACCES: permission denied, mkdir '${parentDir}'`);
      }

      const caughtErr = ['EACCES', 'EPERM', 'EISDIR'].indexOf(err.code) > -1;
      if (!caughtErr || caughtErr && curDir === path.resolve(targetDir)) {
        throw err; // Throw if it's just the last created dir.
      }
    }

    return curDir;
  }, initDir);
}

使用

// Default, make directories relative to current working directory.
mkDirByPathSync('path/to/dir');

// Make directories relative to the current script.
mkDirByPathSync('path/to/dir', {isRelativeToScript: true});

// Make directories with an absolute path.
mkDirByPathSync('/path/to/dir');

解释

[UPDATE] This solution handles platform-specific errors like EISDIR for Mac and EPERM and EACCES for Windows. Thanks to all the reporting comments by @PediT., @JohnQ, @deed02392, @robyoder and @Almenon. This solution handles both relative and absolute paths. Thanks to @john comment. In the case of relative paths, target directories will be created (resolved) in the current working directory. To Resolve them relative to the current script dir, pass {isRelativeToScript: true}. Using path.sep and path.resolve(), not just / concatenation, to avoid cross-platform issues. Using fs.mkdirSync and handling the error with try/catch if thrown to handle race conditions: another process may add the file between the calls to fs.existsSync() and fs.mkdirSync() and causes an exception. The other way to achieve that could be checking if a file exists then creating it, I.e, if (!fs.existsSync(curDir) fs.mkdirSync(curDir);. But this is an anti-pattern that leaves the code vulnerable to race conditions. Thanks to @GershomMaes comment about the directory existence check. Requires Node v6 and newer to support destructuring. (If you have problems implementing this solution with old Node versions, just leave me a comment)

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);
        }
    }
}

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);
}
}

const fs = require('fs');

try {
    fs.mkdirSync(path, { recursive: true });
} catch (error) {
    // this make script keep running, even when folder already exist
    console.log(error);
}

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