EPERM Error using fs.rename()

Here is my code:

exports.post_handler = function(req, res) {
    var photo = req.files.image;
    console.log(photo);
    console.log(__dirname);

    fs.readFile(photo.path, function(err, data) { //I use the path module to join the image path strings
        fs.rename(path.join(__dirname, "public/temp"), path.join(__dirname,"public/images"), function(err) {
            if (err) {
                console.log(err);
                res.redirect("/");
            }
            else {
                console.log("file " + photo.name + "written to uploads folder");
                res.redirect("/home");
            }
        });
    });
}

I'm trying to move an uploaded image file from my temp folder to my uploads folder. I'm using the fs module to do this. After granting full permissions to both files to all users on my PC, I'm getting the following error:

{ [Error: EPERM, rename 'dir\public\temp']
  errno: 50,
  code: 'EPERM',
  path: 'dir\\public\\temp' }

I'm not sure what's going wrong here. Anyone have any ideas?

What your code is trying to do is rename the public/temp directory to public/images. public/images presumably already exists, so you're getting that error. In other words, nowhere in there are you moving the image, you're instead 'moving' (renaming) the directory public/temp to public/images.

You have to use photo.path instead. Use it as the first parameter and then perhaps the second parameter should path.join images directory to path.basename(photos.path).
