Laravel 5.6 route 404 Ошибка при регистрации

Question

Не могу понять проблему с этим маршрутом.вернуть ошибку 404.Я проверил таблицу списка маршрутов, и его маршрут находится внутри.так как я получаю 404, я предполагаю, что есть ошибка маршрутизации, может быть, опечатка, но я не смог ничего увидеть.я обновил этот пост, чтобы показать мои блейд-файлы ...

Answer 1

вы забыли установить пространство имен в классе UserController

Answer 2

Поможет сначала установить php artisan serve, а затем изменить все директивы htdoc, чтобы разрешить все

Answer 3

вы должны запустить "php artisan make: auth"
