toastr程序包致命错误：未捕获RuntimeException：尚未设置外观根

Question

我正在尝试在应用程序中使用Toastr程序包来向用户显示警报。我遵循了教程here，但是现在我无法访问我的应用程序；我遇到此错误：

Fatal error: Uncaught RuntimeException: A facade root has not been set. in C:\xampp\htdocs\MonProjet\vendor\laravel\framework\src\Illuminate\Support\Facades\Facade.php:234 Stack trace: #0 C:\xampp\htdocs\MonProjet\vendor\laravel\framework\src\Illuminate\Foundation\Exceptions\Handler.php(397): Illuminate\Support\Facades\Facade::__callStatic('replaceNamespac...', Array) #1 C:\xampp\htdocs\MonProjet\vendor\laravel\framework\src\Illuminate\Foundation\Exceptions\Handler.php(374): Illuminate\Foundation\Exceptions\Handler->registerErrorViewPaths() #2 C:\xampp\htdocs\MonProjet\vendor\laravel\framework\src\Illuminate\Foundation\Exceptions\Handler.php(289): Illuminate\Foundation\Exceptions\Handler->renderHttpException(Object(Symfony\Component\HttpKernel\Exception\HttpException)) #3 C:\xampp\htdocs\MonProjet\vendor\laravel\framework\src\Illuminate\Foundation\Exceptions\Handler.php(188): Illuminate\Foundation\Exceptions\Handler->prepareResponse(Object(Illuminate\Http\Request), Object(Symfony\Component\HttpKernel\Exception\HttpExcepti in C:\xampp\htdocs\MonProjet\vendor\laravel\framework\src\Illuminate\Support\Facades\Facade.php on line 234

对这个问题有何想法？我已按照步骤操作，但出现此错误。那里怎么了..？

您的问题不清楚。请详细说明， 您可以在渲染前添加@。例：- @toastr（）-> render（）;
