Angular Universal + CkEditor5：未定义窗口

Question

我正在运行使用"@ckeditor/ckeditor5-angular": "1.2.3"和自定义build of CKeditor5的应用程序。我添加了SSR（服务器端渲染-Angular Universal）支持：

ng add @nguniversal/express-engine

并且当我运行npm run dev:ssr时出现以下错误：

  ReferenceError: window is not defined
        at Object../node_modules/@ckeditor/ckeditor5-build-classic/build/ckeditor.js (/Users/user1/angular-ssr/dist/angular-ssr/server/main.js:117340:3242)
        at __webpack_require__ (/Users/user1/angular-ssr/dist/angular-ssr/server/main.js:20:30)

        at __webpack_require__ (/Users/user1/angular-ssr/dist/angular-ssr/server/main.js:20:30)

    A server error has occurred.

有什么方法可以将CkEditor5与Angular Universal集成？还是有人知道任何解决方法？

非常感谢

window对象在服务器端呈现期间不可用，因为您的服务器（即Node.JS）没有window对象-它是浏览器构造。
