我试图将Angular 8应用程序设置为与SSR一起运行，但是当我使用时，我的延迟加载模块在webpack中触发了一些未定义的错误ng serve。在使用Angular 7之前，它运行良好，但转到Angular 8时一切都变了。这是我在运行时遇到的错误（在节点控制台中）

我尝试更改一些tsconfig和angular.json配置，但是我总是遇到相同的错误。常春藤未启用，因为它还会触发生成错误；我认为它是链接的，但我不确定，所以现在我试图在没有常春藤的情况下使它工作

我正在构建我的应用程序npm run build:ssr并为其提供服务npm run serve:ssr
我需要我的应用程序出于SEO的目的使用SSR渲染所有模块和标记，并且希望对问题出在哪里有所帮助。
问题在于，在较旧的设置Universal中，有Angular的两个副本，这使延迟加载系统感到困惑。
您可以通过更新以下内容来手动解决此问题：
package.json
--bundleDependencies all在末尾加上build:client-and-server-bundles
server.ts
删除以下几行
import {enableProdMode} from '@angular/core'; import {ngExpressEngine} from '@nguniversal/express-engine'; import {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader'; enableProdMode(); const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main');然后加
const {AppServerModuleNgFactory, LAZY_MODULE_MAP, ngExpressEngine, provideModuleMap} = require('./dist/server/main');
主服务器
加
export {ngExpressEngine} from '@nguniversal/express-engine'; export {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader';
webpack.server.config.js
加
externals: { './dist/server/main': 'require("./server/main")' }
