gRPC greeter_client不工作

Question

运行greeter_client.rb后，它给出了以下异常

  ruby greeter_client.rb

我不能复制你在这里看到的东西。

一种猜测是，有可能在您的端口"50051“(启动greeter_server.rb的端口)上运行着另一台grpc服务器。

默认情况下，grpc服务器使用SO_REUSEPORT选项绑定端口，因此这种情况是允许的。如果需要，您可以通过使用以下命令构建服务器来禁用SO_REUSEPORT：

s = GRPC::RpcServer.new(server_args: { 'grpc.so_reuseport' => 0 })
