Laravel 5.4は一度歓迎ページを読み込んだ後にエラーを出します。どうしたの？

Question

私はLaravelを学ぼうとしていますが、動作しません。タイトルに示されているように、私はインストールlaravel（composer create-project --prefer-dist laravel/laravel blog経由）をロードしてphp artisan serveを実行し、私は歓迎画面を得ることができます。問題は文字通り一度だけロードされるということです。私は何も変更する必要はなく、ページをリフレッシュすると巨大なスタックトレースが得られます。

Whoops, looks like something went wrong.

私はこの問題に

php artisan clear-compiled 
php artisan cache:clear 
php artisan route:clear 
php artisan view:clear 

を解決しようとするには、次のコマンドを実行してきたし、私はまだ、再びウェルカムページを得ることはありません。

私はopenSUSE Tumbleweedのphp7でLaravel Framework 5.4.33を実行しています。

どうすればよいですか？
