错误：ENOENT：没有这样的文件或目录，重命名（即使该目录存在）

Question

我正在学习express.js一段时间。我只是使用angular.js学习图片上传，当文件上传到temp目录时，我必须将该文件移动到一个新目录。是的，该目录存在。但它仍然显示此错误。

User 572b94b4f30179941f5f7c5dis submittin { fieldName: 'file',
  originalFilename: 'Capture.PNG',
  path: 'C:\\Users\\arfo\\AppData\\Local\\Temp\\zK2-mOXhXflzjrKfxoACnuiw.PNG',
  headers:
   { 'content-disposition': 'form-data; name="file"; filename="Capture.PNG"',
     'content-type': 'image/png' },
  size: 92643,
  name: 'Capture.PNG',
  type: 'image/png' }
{ [Error: ENOENT: no such file or directory, rename 'C:\Users\arfo\AppData\Local\Temp\zK2-mOXhXflzjrKfxoACnuiw.PNG' -> 'C:\Users\arfo\Desktop\all folders\sn\uploads\572b94b4f30179941f5f
7c5d2016-05-06T12:15:52.934ZCapture.PNG']
  errno: -4058,
  code: 'ENOENT',
  syscall: 'rename',

但我有该目录存在

C:\Users\arfo\Desktop\all folders\sn\uploads

这是我的代码 轮廓controller.js

var User = require('../datasets/users');
var fs = require('fs-extra');
var path = require('path');

module.exports.updatePhoto = function (req,res) {
    var file = req.files.file;
    var userId = req.body.userId;
    console.log("User " + userId+"is submittin" , file);    
    var uploadDate = new Date().toISOString();   

    var tempPath = file.path;
    var targetPath = path.join(__dirname, "../../uploads/"+ userId + uploadDate +file.name);
    var savepath = "/uploads/"+userId+ uploadDate +file.name;

    fs.rename(tempPath,targetPath,function (err) {
        if(err){
            console.log(err)
        }else{
            console.log("filemoved");
            /*User.findById(userId,function (err,userData) {
                var user = userData;
                  user.image = savepath;
                  user.save(function (err) {
                      if (err){
                          console.log("Faile ");
                      }else{
                          console.log("Save success");
                      }
                  })
            })*/
        }

    })
};
