Laravel 5.2-错误上传和存储文件

Question

I'm working with laravel 5.1 , I'm trying to upload a file by my form and move to folder images/user/id user, I'm trying like this:

VIEW

<form method="post" action="{{url('account/update/avatar')}}" enctype="multipart/form-data" class="form-horizontal" role="form">
    {csrf_field()}}
     <input id="input-upload-img1" type="file" class="file" data-preview-file-type="text">
     <button type="submit" class="btn btn-success">Cambia</button>
</form>

MY CONTROLLER

public function updateAvatar(Request $request){        
    if ($request->hasFile('image')){             
        $username = Auth::user()->id . '.' . $request->file('image')->getClientOriginalExtension();
        $request->file('image')->move('images/users/', $username);
        $user = new User;
        $user->where('email', '=', Auth::user()->email)
                  ->update(['image' => 'images/users/'.$username]);
            return redirect('account')->with('message-success', 'success!');        
    }else{
            return redirect('account')->with('message-error', 'File error');
    }
}

ROUTES

Route::post('account/update/avatar', 'UserController@updateAvatar');

Actually it return -->

return redirect('account')->with('message-error', 'File error');
