mkdir(): No such file or directory - laravel

I would like to create a directory but I got this error :

ErrorException in Filesystem.php line 390: mkdir(): No such file or directoryErrorException in Filesystem.php line 390: mkdir(): No such file or directory


 in Filesystem.php line 390
at HandleExceptions->handleError('2', 'mkdir(): No such file or directory', 'C:\xampp\htdocs\yatan\yatan\vendor\laravel\framework\src\Illuminate\Filesystem\Filesystem.php', '390', array('path' => 'C:\xampp\htdocs\yatan\yatan\public/assets/images/projects/1/1476592434/', 'mode' => '511', 'recursive' => false, 'force' => false))

my code :

    $to_main_image = time();
    $path = 'assets/images/projects/'.$user_id.'/'.$to_main_image.'/';
    File::makeDirectory(public_path().'/'.$path,0777);
