我对fs的递归选项有问题。mkdir，所以我做了一个函数，做以下工作:

Creates a list of all directories, starting with the final target dir and working up to the root parent. Creates a new list of needed directories for the mkdir function to work Makes each directory needed, including the final function createDirectoryIfNotExistsRecursive(dirname) { return new Promise((resolve, reject) => { const fs = require('fs'); var slash = '/'; // backward slashes for windows if(require('os').platform() === 'win32') { slash = '\\'; } // initialize directories with final directory var directories_backwards = [dirname]; var minimize_dir = dirname; while (minimize_dir = minimize_dir.substring(0, minimize_dir.lastIndexOf(slash))) { directories_backwards.push(minimize_dir); } var directories_needed = []; //stop on first directory found for(const d in directories_backwards) { if(!(fs.existsSync(directories_backwards[d]))) { directories_needed.push(directories_backwards[d]); } else { break; } } //no directories missing if(!directories_needed.length) { return resolve(); } // make all directories in ascending order var directories_forwards = directories_needed.reverse(); for(const d in directories_forwards) { fs.mkdirSync(directories_forwards[d]); } return resolve(); }); }

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;
}

一种选择是使用shelljs模块

npm install shelljs

var shell = require('shelljs');
shell.mkdir('-p', fullPath);

从那一页开始:

可用的选项: P:全路径(如有必要将创建中间dirs)

正如其他人所注意到的，还有其他更专注的模块。但是，除了mkdirp之外，它还有大量其他有用的shell操作(比如which, grep等等…)，并且它可以在windows和*nix上工作

编辑:评论建议这在没有mkdir cli实例的系统上不起作用。事实并非如此。这就是shelljs的重点——创建一个可移植的跨平台shell类函数集。它适用于偶数窗户。

使用reduce，我们可以验证每个路径是否存在，并在必要时创建它，而且我认为这样更容易遵循。编辑，谢谢@Arvin，我们应该使用路径。Sep来获得适当的平台特定路径段分隔符。

const path = require('path');

// Path separators could change depending on the platform
const pathToCreate = 'path/to/dir'; 
pathToCreate
 .split(path.sep)
 .reduce((prevPath, folder) => {
   const currentPath = path.join(prevPath, folder, path.sep);
   if (!fs.existsSync(currentPath)){
     fs.mkdirSync(currentPath);
   }
   return currentPath;
 }, '');

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);
}
}

fs-extra添加了本地fs模块中不包含的文件系统方法。它是fs替换量的下降。

安装fs-extra

$ NPM install——保存fs-extra

const fs = require("fs-extra");
// Make sure the output directory is there.
fs.ensureDirSync(newDest);

有同步和异步选项。
