Javascript 角度9-必须传入NgModule或NgModuleFactory才能进行引导

我将Angular应用程序从v6更新到v9，在测试时它确实正常，但当我将其部署到暂存服务器时，出现以下错误：

必须传入要引导的NgModule或NgModuleFactory

我已经搜索了很多关于它的信息，但我不知道在这里能做些什么

./server.ts：

./webpack.server.config.js

./src/tsconfig.server.json

./src/main.server.ts：

./src/app/app.module.ts

./src/app/app.server.module.ts：

angular.json

使用Ivy，您需要更改server.ts执行引导的方式

看起来您尚未迁移角度ssr文件。我们也遇到了同样的问题，但我们当时没有使用express engine，因此我们最终删除了与ssr server.ts、main.server.ts等相关的文件，。。。并运行以下命令以允许angular修改/创建所有必要的文件

ng add @nguniversal/express-engine

然后，我们修改了server.ts，以便在需要时添加自定义代码

如果您想在不运行命令的情况下手动执行所有操作，请查看一下Ivy，您需要更改server.ts执行引导的方式

我目前实际上也遇到了同样的问题。如果我找到答案，将在此处更新。如何构建应用程序？@varundhariyal NODE\u OPTIONS=\-max old space size=8192\npm run build:modernizer&&ng build-configuration=site dev&&ng run site:server-configuration=site dev&&npm run webpack:dev&&gulp后期处理和npm run build:sitemap./sitemap.xml./dist/browser/&cp./robots.txt./dist/browser/I目前实际上也有同样的问题。如果我找到答案，将在此处更新。如何构建应用程序？@varundhariyal NODE\u OPTIONS=\-max old space size=8192\npm run build:modernizer&&ng build-configuration=site dev&&ng run site:server-configuration=site dev&&npm run webpack:dev&&gulp后期处理和npm run build:sitemap./sitemap.xml./dist/browser/&cp./robots.txt./dist/browser/hi David.Hmmm，是的。我已经尝试过删除所有与之相关的文件，然后运行上面描述的命令。但是，是的，我没有修改server.ts文件。如果我明白了，我应该多做点什么吗？如果我错了，请纠正我。@dmd开发您的server.ts文件不应再引用AppServerModuleNgFactory。如果您已经获得了由命令创建的server.ts的新版本，那么您只需要对该文件的旧版本进行任何自定义，因为我没有对AppServerModuleNgFactory的任何引用，并且命令为我制作了所有文件。在上一个版本中，我没有对server.ts文件做任何更改，它可以自动正常工作。我可以发布server.ts文件，如果你愿意，也许你会看到一些东西。我已经尝试过删除所有与之相关的文件，然后运行上面描述的命令。但是，是的，我没有修改server.ts文件。如果我明白了，我应该多做点什么吗？如果我错了，请纠正我。@dmd开发您的server.ts文件不应再引用AppServerModuleNgFactory。如果您已经获得了由命令创建的server.ts的新版本，那么您只需要对该文件的旧版本进行任何自定义，因为我没有对AppServerModuleNgFactory的任何引用，并且命令为我制作了所有文件。在上一个版本中，我没有对server.ts文件做任何更改，它可以自动正常工作。我可以发布server.ts文件，如果您愿意，也许您会看到一些东西。
