我正在尝试迁移现有的 Angular 应用程序以通过 Angular Universal 使用服务器端渲染。npm build:ssr 可以正常工作，但是在尝试服务：ssr 时，在尝试查找 'google/protobuf/api.proto' 和其他 protos 时会出错。

原型位于 中node_modules/protobufjs/google...，但在尝试为该站点提供服务时显然无法找到。

一些谷歌搜索说我需要放一个，externalDependencies但没有奏效。

版本信息：

如果您使用 Angular Firestore，则需要将其添加为依赖项。这对我有用，在你的 angular.json 文件中。

 "server": {
          "builder": "@angular-devkit/build-angular:server",
          "options": {
            "outputPath": "dist/TeacherKellyUKA/server",
            "main": "server.ts",
            "tsConfig": "tsconfig.server.json",
            "externalDependencies": ["@firebase/firestore"]
          },

如果这不起作用，请尝试此线程：Angular 9 Universal Error: Component 'HeaderComponent' is notsolved:
