您的 AppModule 中缺少 FormsModule 导入。

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { AppComponent } from "./app.component";
import { HeroComponent } from "./hero/hero.component";

@NgModule({
  imports: [BrowserModule, FormsModule],
  declarations: [AppComponent, HeroComponent],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {}
