Question

我使用node-gyp为节点构建我的c ++库，并在网上复制一些例子。

callback.cc

#include <node.h>
#include <v8.h>
using namespace v8;
Handle<Value> Method(const v8::internal::Arguments& args){
  HandleScope scope;
  return scope.Close(String::New("hello,world"));
}
void init(Handle<Object> exports) {
  exports->Set(String::NewSymbol("hello"),FunctionTemplate::New(Method)->GetFunction());
}
NODE_MODULE(hello, init)

binding.gyp

{
  "targets": [
    {
      "target_name": "hello",
      "sources": [ "callback.cc" ]
    }
  ]
}

运行node-gyp configure好的。运行node-gyp build失败，错误：

我不是c ++编码员，请帮助我。

节点：7.9.0

node-gyp：3.6.0

xcode：8.1

mac：10.12.4

GCC：配置为： - prefix = / Applications / Xcode.app / Contents / Developer / usr --with-gxx-include-dir = / usr / include / c ++ / 4.2.1 Apple LLVM 8.0.0版（clang-800.0.42.1）目标：x86_64-apple-darwin16.5.0 线程模型：posix InstalledDir：/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

我已经解决了。因为demo中的c ++代码已经过时了。

新代码如：

ListView

网上有太多过时的例子，我会保留这个问题

node-gyp构建错误“在mac上调用类'v8 :: HandleScope'的受保护构造函数”
