Javascript 如何为node.js创建本机模块

我想创建自己的本机Nodejs模块。我一直在关注并试图理解如何创建本机模块

首先创建hello.cc

#include <node.h>
#include <v8.h>
using namespace v8;
Handle<Value> Method(const Arguments& args) {
 HandleScope scope;
 return scope.Close(String::New("world"));
}

void init(Handle<Object> exports) {
  exports->Set(String::NewSymbol("hello"),
  FunctionTemplate::New(Method)->GetFunction());
}

    NODE_MODULE(hello, init)

然后我运行这些命令

node-gyp configure
node-gyp build

终于创建了hello.js

     var addon = require('./build/Release/hello');
      console.log(addon.hello()); 

这时我犯了一个错误，比如

 module.js:355
 Module._extensions[extension](this, filename);

---

等等。

我试图构建您的示例，但由于V8版本的原因，我无法完成

于是，我又跟着那条路走了。今天，你的例子有点不同。一切正常

我的环境如下：

• 所以：Ubuntu 14.04.2 LTS
• 节点JS v0.12.7
• 节点gyp v2.0.2
• Python 2.7.6
• 通用条款4.8.4
• CPU体系结构：x86_64
• CPU操作模式：32位、64位
• 字节顺序：小端

---

我希望这将是有用的。

我猜您的示例来自以下教程，问题是我遇到了几个编译器错误，这些错误似乎是由于当前版本的

节点上缺少导入造成的：

而
节点gyp
是

macbookproloreto:native admin$ node-gyp -v
v3.3.1

我还没试过，但你读过吗？没有，我会看的。谢谢您在引发错误的行中发布的错误，但实际上不包括错误消息本身，请更新它。谢谢。我去看看
macbookproloreto:native admin$ node -v
v4.2.6

macbookproloreto:native admin$ node-gyp -v
v3.3.1
