如何创建NestJs grpc客户端

正在尝试在docker env上创建NestJs gRPC客户端，但是在编译时我总是会收到此错误

[Nest] 1076   - 2020-05-19 23:59:34   [ClientProxy] The invalid gRPC package (package not found)

我已经尝试重新安装软件包（gRPC，@ grpc / proto-loader和@ nestjs / microservices），

尝试使用文档中提供的两种方法时遇到此问题

<< [第一个方法和@Client装饰器

@Client({ transport: Transport.GRPC, options: { package: 'app', protoPath: join(__dirname, '../../../../../../src/modules/orders/proto/app.proto'), }, }) private client : ClientGrpc private grpcService: IGrpcService; onModuleInit(){ this.grpcService= this.client.getService<IGrpcService>('AppController') }
第二种方法
在appmodule.ts中使用ClientModuleClientsModule.register([{ name:'TEST', transport: Transport.GRPC, options: { package: 'app', protoPath: join(__dirname, '../../../../src/modules/orders/proto/app.proto'), }, }])
原始文件
syntax = "proto3"; package role; service RoleService { rpc CheckPermission (StringMessage) returns (BooleanPayload) {} rpc AddPolicy (StringMessage) returns (BooleanPayload) {} } message StringMessage { repeated string params = 1; } message Role { string id = 1; string codeName = 2; string label = 3; string createdAt = 4; string updatedAt = 5; } message BooleanPayload { bool success = 1; } 回答如下：我已修复它，问题出在我的原始文件包和服务中，我已将其更改为在使用它时控制器的名称。
