Facade 没有实现 getFacadeAccessor 方法

Question

我在尝试将 laravel 9 降级到 8 后收到此错误消息，因为我最近将我的 php 版本从 8 降级到 7.3

In Facade.php line 178:
                                                   
Facade does not implement getFacadeAccessor method.  
                                                   

Script @php artisan package:discover --ansi handling the post-autoload-dump even
returned with error code 1

Answer 1

因为你忘记了 运行

php artisan ui vue --auth

在 composer require laravel/ui

之后

Answer 2

IN app.php 替换
'aliases' => Facade::defaultAliases()->merge([ ])->toArray(),

与：
