我正在尝试将Angular Universal集成到我的Angular6项目中。我遵循了文档（以及同一页上用于Angular Universal的示例项目，https://angular.io/guide/universal）。构建成功且运行正常。但是当我调用localhost:4000时，它抛出以下错误：

TypeError: Cannot assign to read only property 'stopImmediatePropagation' of object '[object Object]'

server.ts

// These are important and needed before anything else
import 'zone.js/dist/zone-node';
import 'reflect-metadata';

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

import * as express from 'express';
import { join } from 'path';

// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();

// Express server
const app = express();

const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');

// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main');

// Express Engine
import { ngExpressEngine } from '@nguniversal/express-engine';
// Import module map for lazy loading
import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';

app.engine('html', ngExpressEngine({
  bootstrap: AppServerModuleNgFactory,
  providers: [
    provideModuleMap(LAZY_MODULE_MAP)
  ]
}));

app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));

// TODO: implement data requests securely
app.get('/api/*', (req, res) => {
  res.status(404).send('data requests are not supported');
});

// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));

// All regular routes use the Universal engine
app.get('*', (req, res) => {
  res.render('index', { req });
});

// Start up the Node server
app.listen(PORT, () => {
  console.log(`Node server listening on http://localhost:${PORT}`);
});

I can post any other files if required.
AppServerModule 应用服务器模块
import { NgModule } from '@angular/core';
import { ServerModule } from '@angular/platform-server';
import { ModuleMapLoaderModule } from '@nguniversal/module-map-ngfactory-loader';

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

@NgModule({
  imports: [
    AppModule,
    ServerModule,
    ModuleMapLoaderModule
  ],
  providers: [
    // Add universal-only providers here
  ],
  bootstrap: [ AppComponent ],
})
export class AppServerModule {}
我们能看到 AppServerModule 的代码吗？ - Reactgular
我已经添加了AppServerModule。感谢您的回复。 - okcomputer_kid
@okcomputer_kid，你能解决上述问题吗？ - Prabhat Mishra
@PrabhatMishra 是的。我已经解决了这个问题。我会把解决方法发布下来。 - okcomputer_kid

看起来这是 platform-server 和 angular/core 版本不兼容的冲突（确保两者版本相同）。将你的 platform-server 降级到与你的 angular/core 相同的版本可能会帮助你解决问题。
