GRPC prbc.h 类未生成objective-c

如何解决GRPC prbc.h 类未生成objective-c

我正在尝试将 GRPC 与 React Native 结合使用。虽然基本的 helloWorld 示例可以很好地使用它。当我向helloworld.proto 文件添加新请求时，它不会生成/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;
  }

我试过了：

pod install

在 pod install 之后，我期待 Helloworld.prbc.h 有 HelloDev 的定义。另一种方式：

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

ReactNativeGrpc 是我项目的 pod

这里是编译器自动生成的文件（即使在运行 pod install 之后也是一样的）

想要在代码中使用更新的 proto 定义，这在这里行不通。

编辑 1：每次清洁和安装都有效，但需要替代方法来避免它。

解决方法

您是否尝试过清理 Cocoapods 缓存？如果没有，请在运行 pod install 之前尝试运行以下命令来清理缓存：

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