angular - 在 Angular 2 应用程序中使用 Material 单选按钮的问题

Question

平台:Ubuntu 14.0.1NPM 版本:4.6.1

我有一个 Angular 2 应用程序，我试图在其中使用 Material 单选按钮。我已经使用以下命令安装了那些:

npm i @angular2-material/radio

我在模块中添加了以下代码:

import { Component } from '@angular/core';
import { FormControl, FormGroup, FormBuilder, Validators } from '@angular/forms';
import { Router } from '@angular/router';
import { MdRadioModule } from '@angular2-material/radio';

以下是 .html 文件的内容(中断):

<md-radio-group>
          <md-radio-button value="1">Option 1</md-radio-button>
          <md-radio-button value="2">Option 2</md-radio-button>
        </md-radio-group>

当我运行应用程序时，我在浏览器的控制台中收到以下错误，我的应用程序在那里中断:

nhandled Promise rejection: Template parse errors:
'md-radio-group' is not a known element:
1. If 'md-radio-group' is an Angular component, then verify that it is part of this module.
2. If 'md-radio-group' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message. (" <md-radio-button value="2">Option 2</md-radio-button>

首先安装@angular/material和@angular/cdk，然后在app.module.ts文件中导入相关包:

import { MatRadioModule } from '@angular/material';
