Angular 意外指令'；信息组件&x27；由模块导入'；DynamicTestModule'；。请添加@NgModule注释

我知道有一个类似的链接指向Stackoverflow的答案，但这并没有解决我的问题，所以我解释了我的情况，我做了ng测试，但失败了，错误如下：

我希望你能帮助我

app.module.ts

---

请注意，您只能导入模块，不能导入组件。在导入部分的

@NgModule

下的

*.module.ts

文件中，检查您是否没有尝试导入

信息组件

是否可以添加

信息组件

代码？我个人有一个问题：行中的默认值是什么：常量：any=（InformationMessages as any）违约是的，我知道：）
