MAT_DIALOG_DATA：错误：必须从注入上下文中调用inject（）错误：必须从注入上下文中调用inject（）

我已经从教程中制作了一个基本的模态对话框，但有点卡住了，加载我的项目可以解决这个错误：

ERROR Error: Uncaught (in promise): Error: inject() must be called from an injection context
Error: inject() must be called from an injection context
    at injectInjectorOnly (core.js:728)

我不确定为什么错误消息会显示为小写字母i inject（）而不是大写字母I @Inject，我正在构造函数中调用

import { Component, NgModule, OnInit } from '@angular/core';
import { Inject } from '@angular/core';
import { MatDialog, MatDialogRef, MatDialogConfig, MatDialogModule, MAT_DIALOG_DATA } from '@angular/material/dialog';

@Component({
  selector: 'term-component',
  templateUrl: './term.component.html'
})
@NgModule({
  imports: [MatDialog, MatDialogRef, MatDialogConfig, MatDialogModule],
  providers: [{
    provide: MatDialog, useValue: {}
  }]
})

export class TermDialog implements OnInit {
  constructor(
    @Inject(MAT_DIALOG_DATA) private modalData: any,
    public dialogRef: MatDialogRef<TermDialog>
  ) {
    console.log(this.modalData);
  }

  ngOnInit() { alert(''); }

  actionFunction() {
    this.closeModal();
  }

  closeModal() {
    this.dialogRef.close();
  }

  onNoClick(): void {
    this.dialogRef.close();
  }
}

所有类似的帮助主题都表示要确保我正在使用大写字母@Inject而不是inject。但是，我确实看到一个建议从“ @ angular / core / testing”而不是“ @ angular / core”导入Inject，我认为这是不可能的吗？

任何帮助将不胜感激，我之前从未在Hello World项目上被困过那么多次。

新：

好的，我想我已经满足了所有5个要求，但仍然看到相同的错误。这是我的app.module.ts：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { RouterModule } from '@angular/router';
import { OverlayModule } from '@angular/cdk/overlay';
import { MatDialogModule } from '@angular/material/dialog';
import { AmplifyAngularModule, AmplifyService } from 'aws-amplify-angular';

import { AppComponent } from './app.component';
import { NavMenuComponent } from './nav-menu/nav-menu.component';
import { HomeComponent } from './home/home.component';
import { CounterComponent } from './counter/counter.component';
import { FetchDataComponent } from './fetch-data/fetch-data.component';

import { TermComponent } from './term.component';
import { TermDialog } from './term-dialog.component';
import { LoginComponent } from './login/login.component';

@NgModule({
  declarations: [
    AppComponent,
    NavMenuComponent,
    HomeComponent,
    CounterComponent,
    FetchDataComponent,
    TermComponent,
    LoginComponent,
    TermDialog
  ],
  imports: [
    AmplifyAngularModule,
    BrowserModule.withServerTransition({ appId: 'ng-cli-universal' }),
    HttpClientModule,
    FormsModule,
    OverlayModule,
    MatDialogModule,
    RouterModule.forRoot([
      { path: '', redirectTo: '/login', pathMatch: 'full' },
      { path: 'login', component: LoginComponent },
      { path: 'counter', component: CounterComponent },
      { path: 'fetch-data', component: FetchDataComponent },
      { path: 'term', component: TermComponent },
      { path: '**', component: LoginComponent }
    ])
  ],
  entryComponents: [
    TermDialog
  ],
  providers: [
    AmplifyService
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

还有我的term.component文件，该文件应该启动term-dialog

import { Component, NgModule } from '@angular/core';
import { MatDialog, MatDialogConfig, MatDialogModule, MatDialogRef, MAT_DIALOG_DATA } from '@angular/material/dialog';
import { TermService } from '../../services/term.service';
import { TermDialog } from './term-dialog.component';
import { compileNgModule } from '@angular/compiler';

@Component({
  selector: 'term-component',
  templateUrl: './term.component.html'
})
@NgModule({
  imports: [MatDialogModule],
  providers: [{ provide: MatDialog, useValue: {} 
  }]
})
export class TermComponent {
  clicked: boolean;
  success: boolean;

  constructor(public dialog: MatDialog, private termService: TermService) {

    this.clicked = false;
  }

  openAddNewTermDialog() {

    const dialogConfig = new MatDialogConfig();
    dialogConfig.disableClose = true;
    dialogConfig.height = "350px";
    dialogConfig.width = "600px";
    dialogConfig.data = {
    };

    const dialogRef = this.dialog.open(TermDialog, dialogConfig);
    dialogRef.afterClosed().subscribe(result => {
      console.log('closed dialog');
      this.success = result;
    })
  }
}
