Objective c GRPC prbc.h类未生成目标-c

我正在尝试将GRPC与react native一起使用。而基本的helloWorld示例可以很好地使用它。当我将新请求添加到Helloworld.proto文件时，它没有生成/更新Helloworld.prbc.h文件

helloworld.proto

  syntax = "proto3";

  option objc_class_prefix = "HLW";

  package helloworld;

  // The greeting service definition.
  service Greeter {
      // Sends a greeting
      rpc SayHello (HelloRequest) returns (HelloReply) {}
      rpc HelloDev (HelloDevRequest) returns (HelloDevReply) {}
  }

  // The request message containing the user's name.
  message HelloRequest {
      string name = 1;
  }

  // The response message containing the greetings
  message HelloReply {
      string message = 1;
  }

  // The request message containing the user's name.
  message HelloDevRequest {
      string name = 1;
  }

  // The response message containing the greetings
  message HelloDevReply {
      string message = 1;
  }

我试过：

pod install

安装pod后，我希望Helloworld.prbc.h对HelloDev有定义。 另一种方式：

protoc --objc_out=Pods/ReactNativeGrpc --objcgrpc_out=Pods/ReactNativeGrpc helloworld.proto

ReactNativeGrpc是我的项目的pod

这是编译器自动生成的文件（即使在运行pod安装后也是如此）

想要在代码中使用更新的proto定义，这在这里不起作用

编辑1：每次清理和安装都有效，但需要其他方法来避免。您是否尝试清理Cocoapods缓存？如果没有，请在运行

pod install

之前尝试运行以下命令以清除缓存：

rm -rf Pods
rm -rf (your_project).xcworkspace
rm Podfile.lock

它工作，但我必须这样做，每次原型文件更新。我正试图避免这种情况。
