Laravel 5.2 $errors未在Blade中出现

因此，我正在遵循Laravel 5基础知识教程，并且我卡在表单验证上。我已经完全按照教程进行了操作，但是我得到了一个未定义的变量：我的创建文章视图中的错误。

在我正在学习的教程中，我在网上找到的内容，他们说错误变量总是在刀片文件中供您使用，所以我不知道我做错了什么？

任何帮助将不胜感激！爱拉拉维尔，除了这个错误！

View
    @if($errors->any())
      <ul class="alert alert-danger">
        @foreach($errors->any() as $error)
          <li>{{$error}}</li>
        @endforeach
      </ul>
    @endif

控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use App\Http\Requests;
use App\Http\Requests\UserRequest as UserRequest;
// use App\Http\Requests\CreateArticleRequest as CreateArticleRequest;
use App\Http\Controllers\Controller;
use Illuminate\View\Middleware\ErrorBinder;

class UserController extends Controller
{
    public function create(){
      return view('pages.signUp');
    }

    public function store(UserRequest $request){
      User::create($request->all());
      return 'the user has been registered!';
      return view('user.profile');
    }

}

请求验证

<?php

namespace App\Http\Requests;

use App\Http\Requests\Request;

class UserRequest extends Request
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name' => 'required',
            'email' => 'required|email',
            'country' => 'required',
            'password' => 'required|min:6',
            'confirm_password' => 'required|same:password',
            'height' => 'required',
            'weight' => 'required',
        ];
    }
}
