laravel-5.7 - 在 Router.php 第 366 行:传递给 Illuminate\Routing\Router::group() 的参数 1 必须是数组类型，

Question

我有更新 Laravel 来自 v5.7至 v5.8现在我的应用程序无法运行。

我因为这个问题更新了它:composer require rebing/graphql-laravel fails

我解决了包不兼容问题，但现在 Laravel 崩溃了:

$ php artisan serve

In Router.php line 366:

  Argument 1 passed to Illuminate\Routing\Router::group() must be of the type array, string given, called in /var/www/masvino/Server-bak/vendor/laravel/framework/src/Illuminate/Support/Facades  
  /Facade.php on line 239

我怀疑 Laravel 的团队改变了这种方法的坚定性:

Illuminate\Routing\Router.php

    /**
     * Create a route group with shared attributes.
     *
     * @param  array  $attributes
     * @param  \Closure|string  $routes
     * @return void
     */
    public function group(array $attributes, $routes) // line 366
    {
        $this->updateGroupStack($attributes);

        // Once we have updated the group stack, we'll load the provided routes and
        // merge in the group's attributes when the routes are created. After we
        // have created the routes, we will pop the attributes off the stack.
        $this->loadRoutes($routes);

        array_pop($this->groupStack);
    }

这是我的 的当前内容composer.json 文件:

我认为问题可能出在这个文件中:
app/Providers/RouteServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Route;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;

class RouteServiceProvider extends ServiceProvider
{
    /**
     * This namespace is applied to your controller routes.
     *
     * In addition, it is set as the URL generator's root namespace.
     *
     * @var string
     */
    protected $namespace = 'App\Http\Controllers';

    /**
     * Define your route model bindings, pattern filters, etc.
     *
     * @return void
     */
    public function boot()
    {
        //

        parent::boot();
    }

    /**
     * Define the routes for the application.
     *
     * @return void
     */
    public function map()
    {
        $this->mapApiRoutes();

        $this->mapWebRoutes();

        //
    }

    /**
     * Define the "web" routes for the application.
     *
     * These routes all receive session state, CSRF protection, etc.
     *
     * @return void
     */
    protected function mapWebRoutes()
    {
        Route::middleware('web')
             ->namespace($this->namespace)
             ->group(base_path('routes/web.php'));
    }

    /**
     * Define the "api" routes for the application.
     *
     * These routes are typically stateless.
     *
     * @return void
     */
    protected function mapApiRoutes()
    {
        Route::prefix('api')
             ->middleware('api')
             ->namespace($this->namespace)
             ->group(base_path('routes/api.php'));
    }
}

不知道 group() 现在哪种格式正确方法。有人可以帮我解决这个问题吗？提前致谢!

正如错误消息所暗示的，通过在 web.php 文件中添加一个空数组来解决问题。

Route::group([], function () {
   Route::get('/', 'HomeController@index')->name('home');
});

我正在使用 Laravel v7。
