使用 shelljs

npm i -D shelljs

const bash = require('shelljs');
bash.cp("-rf", "/path/to/source/folder", "/path/to/destination/folder");

内联版本

node -e "const fs=require('fs');const p=require('path');function copy(src, dest) {if (!fs.existsSync(src)) {return;} if (fs.statSync(src).isFile()) {fs.copyFileSync(src, dest);}else{fs.mkdirSync(dest, {recursive: true});fs.readdirSync(src).forEach(f=>copy(p.join(src, f), p.join(dest, f)));}}const args=Array.from(process.argv); copy(args[args.length-2], args[args.length-1]);" dist temp\dest

或者节点16.x+

node -e "const fs=require('fs');const args=Array.from(process.argv); fs.cpSync(args[args.length-2], args[args.length-1], {recursive: true});" 

在“节点14.20.0”上测试，但假设它在节点10.x上工作?

来自user8894303和pen的回答:https://stackoverflow.com/a/52338335/458321

如果在包中使用，请务必转义引号。json脚本

package.json:

  "scripts": {
    "rmrf": "node -e \"const fs=require('fs/promises');const args=Array.from(process.argv); Promise.allSettled(args.map(a => fs.rm(a, { recursive: true, force: true })));\"",
    "cp": "node -e \"const fs=require('fs');const args=Array.from(process.argv);if (args.length>2){ fs.cpSync(args[args.length-2], args[args.length-1], {recursive: true});}else{console.log('args missing', args);}\""
    "copy": "node -e \"const fs=require('fs');const p=require('path');function copy(src, dest) {if (!fs.existsSync(src)) {return;} if (fs.statSync(src).isFile()) {fs.copyFileSync(src, dest);}else{fs.mkdirSync(dest, {recursive: true});fs.readdirSync(src).forEach(f=>copy(p.join(src, f), p.join(dest, f)));}}const args=Array.from(process.argv);if (args.length>2){copy(args[args.length-2], args[args.length-1]);}else{console.log('args missing', args);}\"",
    "mkdir": "node -e \"const fs=require('fs');const args=Array.from(process.argv);fs.mkdirSync(args[args.length-1],{recursive:true});\"",
    "clean": "npm run rmrf -- temp && npm run mkdir -- temp && npm run copy -- dist temp"
  }

注:RMRF脚本需要14.20节点。X还是12.20.x?

奖金:

deno eval "import { existsSync, mkdirSync, copyFileSync, readdirSync, statSync } from 'node:fs';import { join } from 'node:path';function copy(src, dest) {if (!existsSync(src)) {return;} if (statSync(src).isFile()) {copyFileSync(src, dest);}else{mkdirSync(dest, {recursive: true});readdirSync(src).forEach(f=>copy(join(src, f), join(dest, f)));}}const args=Array.from(Deno.args);copy(args[0], args[1]);" dist temp\dest -- --allow-read --allow-write

Deno支持-> NPM I Deno -bin支持节点中的Deno -bin

支持符号链接的:

const path = require("path");
const {
  existsSync,
  mkdirSync,
  readdirSync,
  lstatSync,
  copyFileSync,
  symlinkSync,
  readlinkSync,
} = require("fs");

export function copyFolderSync(src, dest) {
  if (!existsSync(dest)) {
    mkdirSync(dest);
  }

  readdirSync(src).forEach((entry) => {
    const srcPath = path.join(src, entry);
    const destPath = path.join(dest, entry);
    const stat = lstatSync(srcPath);

    if (stat.isFile()) {
      copyFileSync(srcPath, destPath);
    } else if (stat.isDirectory()) {
      copyFolderSync(srcPath, destPath);
    } else if (stat.isSymbolicLink()) {
      symlinkSync(readlinkSync(srcPath), destPath);
    }
  });
}

解决这个问题最简单的方法是只使用'fs'和'Path'模块和一些逻辑…

如果你只是想设置版本号，根文件夹中的所有文件都复制新名称，即" var v = '您的目录名'"

在文件名的前缀中添加带有文件名的内容。

var fs = require('fs-extra');
var path = require('path');

var c = 0;
var i = 0;
var v = "1.0.2";
var copyCounter = 0;
var directoryCounter = 0;
var directoryMakerCounter = 0;
var recursionCounter = -1;
var Flag = false;
var directoryPath = [];
var directoryName = [];
var directoryFileName = [];
var fileName;
var directoryNameStorer;
var dc = 0;
var route;

if (!fs.existsSync(v)) {
    fs.mkdirSync(v);
}

var basePath = path.join(__dirname, v);


function walk(dir) {

    fs.readdir(dir, function(err, items) {

        items.forEach(function(file) {

            file = path.resolve(dir, file);

            fs.stat(file, function(err, stat) {

                if(stat && stat.isDirectory()) {
                    directoryNameStorer = path.basename(file);
                    route = file;
                    route = route.replace("gd", v);

                    directoryFileName[directoryCounter] = route;
                    directoryPath[directoryCounter] = file;
                    directoryName[directoryCounter] = directoryNameStorer;

                    directoryCounter++;
                    dc++;

                    if (!fs.existsSync(basePath + "/" + directoryName[directoryMakerCounter])) {
                        fs.mkdirSync(directoryFileName[directoryMakerCounter]);
                        directoryMakerCounter++;
                    }
                }
                else {
                    fileName = path.basename(file);
                    if(recursionCounter >= 0) {
                        fs.copyFileSync(file, directoryFileName[recursionCounter] + "/" + v + "_" + fileName, err => {
                            if(err) return console.error(err);
                        });
                        copyCounter++;
                    }
                    else {
                        fs.copyFileSync(file, v + "/" + v + "_" + fileName, err => {
                            if(err) return console.error(err);
                        });
                        copyCounter++;
                    }
                }
                if(copyCounter + dc == items.length && directoryCounter > 0 && recursionCounter < directoryMakerCounter-1) {
                    console.log("COPY COUNTER:             " + copyCounter);
                    console.log("DC COUNTER:               " + dc);
                    recursionCounter++;
                    dc = 0;
                    copyCounter = 0;
                    console.log("ITEM DOT LENGTH:          " + items.length);
                    console.log("RECURSION COUNTER:        " + recursionCounter);
                    console.log("DIRECOTRY MAKER COUNTER:  " + directoryMakerCounter);
                    console.log(": START RECURSION:        " + directoryPath[recursionCounter]);
                    walk(directoryPath[recursionCounter]); //recursive call to copy sub-folder
                }
            })
        })
    });
}

walk('./gd', function(err, data) { // Just pass the root directory which you want to copy
    if(err)
        throw err;
    console.log("done");
})

是的，ncp很酷…

你可能想要/应该承诺它的功能，让它超级酷。当你这样做的时候，把它添加到一个工具文件中以重复使用它。

下面是一个工作版本，它是异步的，并使用承诺。

文件index.js

const {copyFolder} = require('./tools/');

return copyFolder(
    yourSourcePath,
    yourDestinationPath
)
.then(() => {
    console.log('-> Backup completed.')
}) .catch((err) => {
    console.log("-> [ERR] Could not copy the folder: ", err);
})

文件tools.js

const ncp = require("ncp");

/**
 * Promise Version of ncp.ncp()
 *
 * This function promisifies ncp.ncp().
 * We take the asynchronous function ncp.ncp() with
 * callback semantics and derive from it a new function with
 * promise semantics.
 */
ncp.ncpAsync = function (sourcePath, destinationPath) {
  return new Promise(function (resolve, reject) {
      try {
          ncp.ncp(sourcePath, destinationPath, function(err){
              if (err) reject(err); else resolve();
          });
      } catch (err) {
          reject(err);
      }
  });
};

/**
 * Utility function to copy folders asynchronously using
 * the Promise returned by ncp.ncp().
 */
const copyFolder = (sourcePath, destinationPath) => {
    return ncp.ncpAsync(sourcePath, destinationPath, function (err) {
        if (err) {
            return console.error(err);
        }
    });
}
module.exports.copyFolder = copyFolder;

我写了这个函数用于在目录之间递归地复制(copyFileSync)或移动(renameSync)文件:

// Copy files
copyDirectoryRecursiveSync(sourceDir, targetDir);
// Move files
copyDirectoryRecursiveSync(sourceDir, targetDir, true);


function copyDirectoryRecursiveSync(source, target, move) {
    if (!fs.lstatSync(source).isDirectory())
        return;

    var operation = move ? fs.renameSync : fs.copyFileSync;
    fs.readdirSync(source).forEach(function (itemName) {
        var sourcePath = path.join(source, itemName);
        var targetPath = path.join(target, itemName);

        if (fs.lstatSync(sourcePath).isDirectory()) {
            fs.mkdirSync(targetPath);
            copyDirectoryRecursiveSync(sourcePath, targetPath);
        }
        else {
            operation(sourcePath, targetPath);
        }
    });
}
