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。

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)

我知道这是一个老问题，但是nodejs v10.12.0现在通过将递归选项设置为true在本地支持这个选项。fs.mkdir

// Creates /tmp/a/apple, regardless of whether `/tmp` and /tmp/a exist.
fs.mkdir('/tmp/a/apple', { recursive: true }, (err) => {
  if (err) throw err;
});

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!')
})

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

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
