HostResourceResolver中的错误有什么问题：在app.component.ts的上下文中无法解析./server2.component.html

Question

我检查了现有答案，但是这些答案不起作用。

ERROR in ./src/app/app.module.ts 12:12-24 "export 'AppComponent' was not found in './app.component'
ERROR in ./src/app/app.module.ts 20:20-32 "export 'AppComponent' was not found in './app.component'
ERROR in Host ResourceResolver: could not resolve ./server2.component.html in context of C:/Users/HOME/My-first-app/src/app/app.component.ts)
