我不知道这个代码有什么问题，我尝试了一切来改变拼写错误再次重新创建项目，但我卡在这里，我不知道我错过了什么。 enter image description here

Answer 1

如果我是对的，我认为这是一个错误的错误。

RegistrationForm.php location = Larabook \ App \ Forms所以命名空间应该是

namespace Larabook\App\Forms;

Answer 2

您应该尝试运行：

composer dump-autoload

为您的项目生成新的类映射

Answer 3

使用namespace Larabook\App\Forms;。

或在文件larabook中定义app>Larabook>Forms>RegistrationForm.php，然后只需使用namespace Larabook\Forms;。

请勿忘记使用composer dump-autoload -o，其中-o用于优化。

ReflectionException类Larabook \ Forms \ RegistrationForm不存在
