我在项目中使用Angular 7，我想将SSR(服务器端渲染(添加到我的项目中。我使用命令
ng add @nguniversal/express-engine --clientProject matngular
所以他们添加了一堆文件。然后我继续命令
npm run build:ssr
建造成功了。所以我开始使用命令来提供dist文件夹
npm run serve:ssr
所以我得到了类似下面的错误
D:git-workspacethe-seagate-suiteseagate-webdistserver.js:205940

我已经尝试了Stackoverflow的解决方案，接受了答案。但没有一个对我有用。我的Angular项目版本是7.3.6，typeScript是3.2.4。谢谢
Adam，
正如Angular文档所述：
由于Universal应用程序不会在浏览器中执行服务器上可能缺少浏览器API和功能。
例如，服务器端应用程序不能仅引用浏览器全局对象，如窗口、文档、导航器或位置。
Angular在这些对象上提供了一些可注入的抽象，例如作为位置或文件；它可以充分替代这些API。如果Angular没有提供它，就有可能编写新的抽象在浏览器中委托给浏览器API和在服务器上的替代实现(也称为填充(。
您可以尝试通过组件或服务的构造函数中的角度依赖注入来注入Document实例：
constructor(@Inject(DOCUMENT) private document: Document) {}
