无法绑定到 'ngModel'，因为它不是 'input' 的已知属性。测试 .spec.ts

Question

我已经链接到另一张票。这个错误只发生在测试中，我已经为每个链接的消息导入了 FormsModule。我正在使用 Angular 2.2.1.

ngModel 未在 'ng test' 中定义我导入了 FormsModule 和 ReactiveFormsModule 但没有效果。我已经对此进行了 24 小时的研究，但离我还差得很远。大多数与升级有关，我擦除并重新启动了同样的问题，使用 ng generate 创建时测试模板非常简单。

我使用 angular cli 来构建我的应用程序（并重建它...）并且我添加了表单导入，因为它看起来很重要。

这是我的简单模板，请注意，它不是表格而是 div，这没有区别。 'ng serve' 看起来合理，因此代码在理论上是正确的。

这是我的表格...

<form class="form-horizontal">
  <div class="form-group">
    <label class="col-sm-2 control-label" for='line1'>Address 1</label>
    <div class="col-sm-10">
      <input type="text" class="form-control" placeholder="Line 1" id='line1' [(ngModel)]='address.line1' required>
    </div>
  </div>
  <div class="form-group">
    <label for="inputPassword" class="col-sm-2 control-label" for='line2'>Address 2</label>
    <div class="col-sm-10">
      <input type="text" class="form-control" id="line2" placeholder="Line 2" [(ngModel)]='address.line2'>
    </div>
  </div>
  <div class="form-inline">
    <div class="form-group">
      <label for="inputPassword" class="col-sm-2 control-label" for='Suburb'>Suburb</label>
      <div class="col-sm-6">
        <input type="text" class="form-control" id="suburb" placeholder="Suburb" [(ngModel)]='address.suburb'>
      </div>
      <div class="col-sm-2">
        <input type="text" class="form-control" id="State" placeholder="State" [(ngModel)]='address.state'>
      </div>
      <div class="col-sm-2">
        <input type="text" class="form-control" id="postcode" placeholder="Postcode" [(ngModel)]='address.postcode'>
      </div>
    </div>
  </div>
</form>

这是我的测试规范，经过大量研究，我添加了 CommonModule 和 ReactiveFormsModule 以及 FormsBuilder，但并不高兴。

    /* tslint:disable:no-unused-variable */

import { TestBed, async } from '@angular/core/testing';
import { CommonModule } from '@angular/common';
import { FormsModule, ReactiveFormsModule, FormBuilder } from '@angular/forms';


import { AddressComponent } from './address.component';
import { Address } from './address';

describe('Component: Address', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [AddressComponent],
      imports: [CommonModule, ReactiveFormsModule],
      providers: [FormBuilder]
    });
  });

  it('should create an instance', () => {
    let component = new AddressComponent();
    expect(component).toBeTruthy();
  });

  it('should handle address', () => {
    expect(true).toBeTruthy();
  });

});

这是我的组件。很简单...

import { Input, Component, OnInit } from '@angular/core';
import { Address } from './address';

@Component({
  selector: 'app-address',
  templateUrl: './address.component.html',
  styleUrls: ['./address.component.css'],
})

export class AddressComponent implements OnInit {

  @Input() address: Address;

  constructor() { }

  ngOnInit() {
  }

}

我得到的错误是：

"): AddressComponent@4:78
Can't bind to 'ngModel' since it isn't a known property of 'input'. ("iv class="col-sm-10">
      <input type="text" class="form-control" id="line2" placeholder="Line 2" [ERROR ->][(ngModel)]='address.line2'>

同时添加 FormsModule

imports: [CommonModule, ReactiveFormsModule, FormsModule],

无法绑定到 'ngModel'，因为它不是 'input' 的已知属性。测试 .spec.ts
