我正在尝试运行和构建我的服务器端渲染角度项目。一旦我在我的机器上本地运行项目并在 Web 浏览器中打开它，我会收到以下错误：

Error: No NgModule metadata found for 'AppServerModule'.

我已经进行了一些检查和研究，但我无法找到问题所在。我相信这是相对简单的事情，但希望能提供任何帮助。我将提供有关其他一些文件的一些详细信息。先感谢您！

这是 src/main.server.ts 文件

import { enableProdMode } from '@angular/core';

import { environment } from './environments/environment';

if (environment.production) {
  enableProdMode();
}

export { AppServerModule } from './app/app.server.module';
export { renderModule, renderModuleFactory } from '@angular/platform-server';

这是 src/app/app.server.module 文件

import { NgModule } from '@angular/core';
import { ServerModule } from '@angular/platform-server';

import { AppModule } from './app.module';
import { AppComponent } from './app.component';

@NgModule({
  imports: [
    AppModule,
    ServerModule,
  ],
  bootstrap: [AppComponent],
})
export class AppServerModule {}

'import' 而不是 'export' 将修复它

ng10 通用项目有同样的问题。就我而言，我已将 bundleDependencies 设置为 false，并将其恢复为 true 清除了上述错误。下面的 angular.json 片段。

"server": {
  "builder": "@angular-devkit/build-angular:server",
  "options": {
    "outputPath": "dist/server",
    "main": "server.ts",
    "tsConfig": "tsconfig.server.json",
    "bundleDependencies": true
  },
