如何修复将调用迁移到未定义的方法migrating \Session\Store：：getToken时出现的错误？

Question

我尝试将laravel 5.0应用程序更新到5.7，并按步骤I移动步骤被错误停止：

    Call to undefined method Illuminate\Session\Store::getToken() (View: /var/www/html/YoutubeAPI_Demo-57/resources/views/videos.blade.php)

in HtmlServiceProvider.php line 51
at CompilerEngine->handleViewException(object(FatalThrowableError), 1)

我找到了一个文件：

vendor/illuminate/html/HtmlServiceProvider.php with method which triggered error: 
    /**
     * Register the form builder instance.
     *
     * @return void
     */
    protected function registerFormBuilder()
    {
        $this->app->singleton('form', function($app)
        {
            $form = new FormBuilder($app['html'], $app['url'], $app['session.store']->getToken());

            return $form->setSessionStore($app['session.store']);
        });
    }

你能给出一个如何修复这个错误的提示吗？

提前感谢！
