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。

像这样干净:)

function makedir(fullpath) {
  let destination_split = fullpath.replace('/', '\\').split('\\')
  let path_builder = destination_split[0]
  $.each(destination_split, function (i, path_segment) {
    if (i < 1) return true
    path_builder += '\\' + path_segment
    if (!fs.existsSync(path_builder)) {
      fs.mkdirSync(path_builder)
    }
  })
}

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;
 }, '');

Exec在windows上可能很乱。还有一个更“nodie”的解决方案。基本上，您有一个递归调用来查看目录是否存在，并深入子目录(如果存在)或创建它。下面是一个函数，它将创建子函数，并在完成时调用一个函数:

fs = require('fs');
makedirs = function(path, func) {
 var pth = path.replace(/['\\]+/g, '/');
 var els = pth.split('/');
 var all = "";
 (function insertOne() {
   var el = els.splice(0, 1)[0];
   if (!fs.existsSync(all + el)) {
    fs.mkdirSync(all + el);
   }
   all += el + "/";
   if (els.length == 0) {
    func();
   } else {
     insertOne();
   }
   })();

}

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(); }); }

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);
        }
    }
}
