我将把所有涉及的函数(即重命名，复制，断开链接)彼此分离，以获得灵活性，并承诺一切，当然:

const renameFile = (path, newPath) => 
  new Promise((res, rej) => {
    fs.rename(path, newPath, (err, data) =>
      err
        ? rej(err)
        : res(data));
  });

const copyFile = (path, newPath, flags) =>
  new Promise((res, rej) => {
    const readStream = fs.createReadStream(path),
      writeStream = fs.createWriteStream(newPath, {flags});

    readStream.on("error", rej);
    writeStream.on("error", rej);
    writeStream.on("finish", res);
    readStream.pipe(writeStream);
  });

const unlinkFile = path => 
  new Promise((res, rej) => {
    fs.unlink(path, (err, data) =>
      err
        ? rej(err)
        : res(data));
  });

const moveFile = (path, newPath, flags) =>
  renameFile(path, newPath)
    .catch(e => {
      if (e.code !== "EXDEV")
        throw new e;

      else
        return copyFile(path, newPath, flags)
          .then(() => unlinkFile(path));
    });

moveFile只是一个方便的函数，我们可以分别应用这些函数，例如，当我们需要更细粒度的异常处理时。

如果你喜欢使用外部库，Shelljs是一个非常方便的解决方案。

命令: Mv ([options，] source, destination)

可用的选项:

-f: force(默认行为)

-n:防止覆盖

const shell = require('shelljs');
const status = shell.mv('README.md', '/home/my-dir');
if(status.stderr)  console.log(status.stderr);
else console.log('File moved!');

本地使用nodejs

var fs = require('fs')

var oldPath = 'old/path/file.txt'
var newPath = 'new/path/file.txt'

fs.rename(oldPath, newPath, function (err) {
  if (err) throw err
  console.log('Successfully renamed - AKA moved!')
})

(注意:“如果您正在跨分区或使用不支持移动文件的虚拟文件系统，这将不起作用。[…——Flavien Volken 15年9月2日12:50)

下面是一个使用util的例子。我如何移动文件a到不同的分区或设备在Node.js?

var fs = require('fs'),
    util = require('util');

var is = fs.createReadStream('source_file')
var os = fs.createWriteStream('destination_file');

util.pump(is, os, function() {
    fs.unlinkSync('source_file');
});
