获取错误选项“service=grpc-web”无法识别

Question

我正在使用带有角度的 grpc。 我的 package.json：

{
  "name": "angular13",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "watch": "ng build --watch --configuration development",
    "test": "ng test"
  },

    "@angular/platform-browser-dynamic": "~13.0.0-next.0",
    "@angular/router": "~13.0.0-next.0",
    "@auth0/angular-jwt": "^5.0.2",

  },

    "karma": "~6.3.0",
    "karma-chrome-launcher": "~3.1.0",
    "karma-coverage": "~2.0.3",
    "karma-jasmine": "~4.0.0",
    "karma-jasmine-html-reporter": "~1.7.0",
    "typescript": "~4.4.3"
  }
}

我正在运行以下命令来生成原型文件

protoc --plugin=protoc-gen-ts="C:\Users\...\source\...\node_modules\.bin\protoc-gen-ts.cmd" --js_out="import_style=commonjs,binary:C:\Users\...\source\...\src\app\api\protos\generated" --ts_out="service=grpc-web:C:\Users\...\source\...\src\app\api\protos\generated" plc.proto

出现此错误：

Option "service=grpc-web" not recognized.

我重新安装了相关的 npms ts-protoc-gen、google-protobuf、@types/google-protobuf 和 @improbable-eng/grpc-web，但仍然无法正常工作。 谢谢！
