我已经更改了我的一个类，添加了一个方法和一些包括，在这样做之后，我收到了很多未定义或丢失的错误，这些错误在此之前没有问题并且运行良好。
这是我得到错误的头文件：

资产加载器.h 

#ifndef LS_ASSETLOADER_H
#define LS_ASSETLOADER_H
#include <assimp/Importer.hpp>
#include <assimp/scene.h>
#include <assimp/postprocess.h>
#include <assimp/types.h>

#include <glm/glm.hpp>
#include <vector>

//these are the headers that give me problems
//#include "scene.h" 
//#include "model.h"



//the 2 methods below are commented so i don't get errors for missing Scene
class AssetLoader {
    //void importScene(aiNode* node, ls::Scene* scene, const aiScene* aScene);

public:
    bool loadMesh(
        const char* path,
        std::vector<glm::vec3>* vertices,
        std::vector<glm::vec3>* normals,
        std::vector<glm::vec2>* uvs
    );

//  bool loadScene(const char* path, ls::Scene* scene);
};

#endif

另外两个是场景和模型标题：

场景.h

#ifndef LS_SCENE_H
#define LS_SCENE_H
#include <vector>
#include "camera.hpp"
#include "light.h"
#include "model.h"

namespace ls {
    class Scene;
}

class ls::Scene {
    std::vector<Camera*> _camera;
    std::vector<Light*> _light;
    std::vector<Model*> _model;

    unsigned int _activeCamera;

public:
    Scene();

    void addCamera(Camera* camera);
    void addLight(Light* light);
    void addModel(Model* model);

    void draw();
};

#endif

模型.h 

#ifndef LS_MODEL_H
#define LS_MODEL_H
#include "mesh.h"
#include "material.h"
#include "renderer.h"
#include <glm/glm.hpp>

class Model {

    Mesh* _mesh;
    Material* _material;
    Renderer* _renderer;

    glm::mat4 _transform;

public:
    Model(Mesh* mesh, Material* material);
    Renderer* renderer() const;
    glm::mat4 transform() const;

    void setPosition(glm::vec3 position);
    void translate(glm::vec3 translation);
    void scale(glm::vec3 factor);
    void setRotation(glm::vec3 axis, float angle);
};

#endif

网格.h 

#ifndef LS_MESH_H
#define LS_MESH_H
#include <vector>
#include <glm/glm.hpp>
#include "assetloader.h"
#include "texture2D.h"

class Mesh {
    std::vector<glm::vec3> _vertices;
    std::vector<glm::vec3> _normals;
    std::vector<glm::vec2> _uvs;

public:
    Mesh(const char* path);
    Mesh();

    int numVertices() const;
    std::vector<glm::vec3> vertices() const;
    void setVertices(std::vector<glm::vec3> vertices);
    std::vector<glm::vec2> uvs() const;
    void setUVs(std::vector<glm::vec2> uvs);
    void setNormals(std::vector<glm::vec3> normals);
    std::vector<glm::vec3> normals() const;


};

#endif

我没有包含 .cpp 文件，因为我认为没有问题（我没有从他们上次工作时修改它们）。
这是我得到的一些错误示例（我没有包括所有这些示例，因为它们太多并且与这些类似）：

看起来您已包含model.h在mesh.h
您需要Mesh在 model.h中转发声明

class Mesh;
class Model {
