为什么我不能从同一目录中的另一个文件中 #include 我的类?

我有三个文件，结构如下

- src/
- events
- ...
- Event.cpp
- Event.h
- EventPtr.h
- ...

问题是EventPtr.h内部的#include Event.h似乎不起作用。这是代码：

事件.h

#ifndef POKERSIMULATIONSINCPP_EVENT_H
#define POKERSIMULATIONSINCPP_EVENT_H
#include <iostream>
#include "game/Table.h"
#include "players/Player.h"
namespace events {
enum TargetType {
Dealer, Table, None, Players
};

class Event {
private:
TargetType target = None;
std::string description = "Base event class";
bool done = false;
public:
~Event();
Event();
TargetType getTarget();
std::string getDescription();
bool getDone();
};

}
#endif //POKERSIMULATIONSINCPP_EVENT_H

事件.cpp

#include "Event.h"
#include <iostream>
namespace events {
TargetType Event::getTarget() {
return target;
}
std::string Event::getDescription() {
return description;
}
bool Event::getDone() {
return done;
}
Event::~Event() = default;
Event::Event() = default;
}

事件Ptr.h

#ifndef POKERSIMULATIONSINCPP_EVENTPTR_H
#define POKERSIMULATIONSINCPP_EVENTPTR_H
#include <memory>
#include "events/Event.h"
namespace events {
typedef std::shared_ptr<Event> EventPtr;
}
#endif //POKERSIMULATIONSINCPP_EVENTPTR_H

这给出了以下错误：

错误

D:/PokerSimulationsInCpp/src/events/EventPtr.h:13:29: error: 'Event' was not declared in this scope
typedef std::shared_ptr<Event> EventPtr;

我也尝试过这个EventPtr.h

EventPtr.h，第二次尝试

#ifndef POKERSIMULATIONSINCPP_EVENTPTR_H
#define POKERSIMULATIONSINCPP_EVENTPTR_H
#include <memory>
#include "events/Event.h"
#include "Event.h"
namespace events {
typedef std::shared_ptr<events::Event> EventPtr;
}
#endif //POKERSIMULATIONSINCPP_EVENTPTR_H

这给出了以下错误：

D:/PokerSimulationsInCpp/src/events/EventPtr.h:14:37: error: 'Event' is not a member of 'events'
typedef std::shared_ptr<events::Event> EventPtr;

有人知道发生了什么吗？
