简单的可复制示例：
binding.gyp：
{
"targets": [
{
"target_name": "hello",
"sources": [ "./hello.cc" ],
"cflags_cc": [ "-mavx2" ]
}
]
}
hello.cc
// hello.cc
#include <node.h>
namespace demo {
using v8::FunctionCallbackInfo;
using v8::Isolate;
using v8::Local;
using v8::NewStringType;
using v8::Object;
using v8::String;
using v8::Value;
void Method(const FunctionCallbackInfo<Value>& args) {
Isolate* isolate = args.GetIsolate();
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)
} // namespace demo
假设我想向C ++编译器添加-mavx2标志。但是node-gyp只会忽略它，而不会在编译器上使用它。
要弄清楚我跑了node-gyp rebuild --verbose：
完整日志（您可能不需要）：

其中不包含-mavx2标志。我在做什么错了？
