my code :

  if (_.isEmpty(req.files) == false) {
      var tp = avatar_folder+req.files.file.name;
      fs.renameSync(req.files.file.path, tp, function(err){});
      var avatar = req.files.file.name;
      }

code work on another distro like elementary os, but when i run project on debian jessie or ubuntu 16 LTS that error result on terminal.

any body can't help ? that code just run perfectly on elementary os and arch.

Same problem. Workaround: Read the temp file, write the file in new location and remove the temp file:

        // Read the file
        fs.readFile(oldpath, function (err, data) {
            if (err) throw err;
            console.log('File read!');

            // Write the file
            fs.writeFile(newpath, data, function (err) {
                if (err) throw err;
                res.write('File uploaded and moved!');
                res.end();
                console.log('File written!');
            });

            // Delete the file
            fs.unlink(oldpath, function (err) {
                if (err) throw err;
                console.log('File deleted!');
            });
        });

You can use 'mv' packgage to resolve this issue Link NPM: https://www.npmjs.com/package/mv How to use:

Replace some old code with fs.rename:

    fs.rename(temp_path, target_path, (err) => {
        if (err) {
            console.log('> FileServer.jsx | route: "/files/upload" | err:', err);
            throw err;
        }
    });

With:

    const mv = require('mv');
    mv(temp_path, target_path, function (err) {
        if (err) {
            console.log('> FileServer.jsx | route: "/files/upload" | err:', err);
            throw err;
        }
    });

var http = require('http');
var formidable = require('formidable');
var fs = require('fs');
var mv = require('mv');

http.createServer(function (req, res) {
  if (req.url == '/fileupload') {
    var form = new formidable.IncomingForm();
    form.parse(req, function (err, fields, files) {
      var oldpath = files.filetoupload.path;
     console.log(oldpath);
      var newpath = 'F:/change path to your project dir/' + files.filetoupload.name;
      mv(oldpath, newpath, function (err) {
        if (err) throw err;
        res.write('File uploaded and moved!');
        res.end();
      });
 });
  } else {
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.write('<form action="fileupload" method="post" enctype="multipart/form-data">');
    res.write('<input type="file" name="filetoupload"><br>');
    res.write('<input type="submit">');
    res.write('</form>');
    return res.end();
  }enter code here
}).listen(8080);
