c++ - Node JS - 模块没有自行注册

Question

我浏览了不同的帖子，其中大多数建议重建/重新安装/更新 npm，我试过了，但没有帮助。

我正在尝试使用 C++ 的 node.js 示例，下面是文件详细信息
测试 Node .cpp

#include<iostream>
class TestNode {
public:
    void printHelloW() {
        std::cout << "Hello World!!!";
    }
};

绑定(bind).gyp

{
  "targets": [
    {
      "target_name": "newexample",
      "sources": [ "TestNode.cpp" ]
    }
  ]
}

现在执行并抛出错误，指出模块未自行注册。

编写 node.js 插件并不是那么简单，您需要显式导出函数并调用适当的宏以将插件注册到 Node 的模块系统。阅读 Addons documentation获取更多信息和示例。
