我正在尝试向我们的应用程序添加i18n支持，并按照https://angular.io/guide/i18n中所述并通过https://angular.io/generated/zips/i18n/i18n.zip进行演示的步骤
在该示例中，一切正常，包括调用
ng xi18n
但是，在我们的项目中，每当我尝试从源中提取i18n密钥时，都会收到以下错误消息：
npm run extract
在“ AppModule”函数调用的模板编译期间发生错误时出现错误 装饰器中不支持，但“ ZisAuthenticationModule”为 叫。
起初，我认为构建和启动应用程序可以正常工作：
npm run build
npm run build:de
npm run build:fr
npm run start
npm run start:fr
一切正常，除了我显然忘记将"aot": true条目添加到angular.json中的所有那些配置中。添加这些内容后，即使构建它仍然可以正常运行（并且始终将AOT设置为true），我现在都无法再运行我的应用程序。
我到处搜索Google，并在github和stackoverflow上找到了各种文章，但没有找到任何对我有帮助的东西。
我尝试执行类似的错误
ng build --configuration production
当environment.prod.ts文件缺少变量keycloakClientId时。但是，现在所有环境文件都包含此变量，所以我没有主意。
有人能指出我正确的方向吗？
这是我的文件：
