该特性已在10.12.0版本中添加到node.js中，因此只需将选项{recursive: true}作为第二个参数传递给fs.mkdir()调用即可。 请参阅官方文档中的示例。

不需要外部模块或自己的实现。

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!')
})

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(); }); }

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;
 }, '');

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('/')); 
        }
    });
}

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;
}
