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;
});

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);
}

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。

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(); }); }

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();
   }
   })();

}

您可以使用下一个函数

const recursiveUpload =(路径:字符串)=> { Const paths = path.split("/")

const fullPath = paths.reduce((accumulator, current) => {
  fs.mkdirSync(accumulator)
  return `${accumulator}/${current}`
  })

  fs.mkdirSync(fullPath)

  return fullPath
}

它的作用是:

创建路径变量，它将每个路径单独存储为数组的一个元素。 在数组中每个元素的末尾添加"/"。 形成循环: 从索引从0到当前迭代的数组元素的连接中创建一个目录。基本上，它是递归的。

希望有帮助!

顺便说一下，在Node v10.12.0中，可以通过将递归路径创建作为附加参数来使用。

fs。mkdir(“/ tmp / /苹果”,{递归:真},(err) = > { 如果(错误)抛出错误; })；
