环境：
系统：centos 7
node: v12.13.0
1.目录结构

其中，12.13.0文件夹为node v12.13.0版本的头文件
2.hello.cc
// hello.cc
#include <node.h>

args.GetReturnValue().Set(String::NewFromUtf8(
isolate, "world", NewStringType::kNormal).ToLocalChecked());
}
void Initialize(Local<Object> exports) {
NODE_SET_METHOD(exports, "hello", Method);
}
NODE_MODULE(NODE_GYP_MODULE_NAME, Initialize)
} // 命名空间示例
3.index.js
//hello.js
var addon = require('./build/hello.node');
console.log(addon.hello()); // 'world'
