如果您试图移动或重命名一个node.js源文件，请尝试https://github.com/viruschidai/node-mv。它将更新所有其他文件中对该文件的引用。

这个例子摘自:Node.js in Action

move()函数，如果可能，将重命名或返回到复制

var fs = require('fs');

module.exports = function move(oldPath, newPath, callback) {

    fs.rename(oldPath, newPath, function (err) {
        if (err) {
            if (err.code === 'EXDEV') {
                copy();
            } else {
                callback(err);
            }
            return;
        }
        callback();
    });

    function copy() {
        var readStream = fs.createReadStream(oldPath);
        var writeStream = fs.createWriteStream(newPath);

        readStream.on('error', callback);
        writeStream.on('error', callback);

        readStream.on('close', function () {
            fs.unlink(oldPath, callback);
        });

        readStream.pipe(writeStream);
    }
}

使用mv节点模块，它将首先尝试执行fs。重命名，然后退回到复制，然后取消链接。

就像上面的回答中所说的那样，我的2分:copy()方法不应该在没有轻微调整的情况下原样用于复制文件:

function copy(callback) {
    var readStream = fs.createReadStream(oldPath);
    var writeStream = fs.createWriteStream(newPath);

    readStream.on('error', callback);
    writeStream.on('error', callback);

    // Do not callback() upon "close" event on the readStream
    // readStream.on('close', function () {
    // Do instead upon "close" on the writeStream
    writeStream.on('close', function () {
        callback();
    });

    readStream.pipe(writeStream);
}

复制函数封装在Promise中:

function copy(oldPath, newPath) {
  return new Promise((resolve, reject) => {
    const readStream = fs.createReadStream(oldPath);
    const writeStream = fs.createWriteStream(newPath);

    readStream.on('error', err => reject(err));
    writeStream.on('error', err => reject(err));

    writeStream.on('close', function() {
      resolve();
    });

    readStream.pipe(writeStream);
  })

但是，请记住，如果目标文件夹不存在，文件系统可能会崩溃。

对于8.0.0以上的Node版本使用承诺:

const {promisify} = require('util');
const fs = require('fs');
const {join} = require('path');
const mv = promisify(fs.rename);

const moveThem = async () => {
  // Move file ./bar/foo.js to ./baz/qux.js
  const original = join(__dirname, 'bar/foo.js');
  const target = join(__dirname, 'baz/qux.js'); 
  await mv(original, target);
}

moveThem();

fs-extra模块允许你用它的move()方法来做这件事。我已经实现了它，它工作得很好，如果你想完全移动一个文件从一个目录到另一个-即。从源目录中删除文件。应该适用于大多数基本情况。

var fs = require('fs-extra')

fs.move('/tmp/somefile', '/tmp/does/not/exist/yet/somefile', function (err) {
 if (err) return console.error(err)
 console.log("success!")
})
