You don't have backticks or quotes in your template: 您的模板中没有反引号或引号：

The template is a multi-line string within ECMAScript 2015 backticks ( ). The backtick ( 模板是ECMAScript 2015反引号（ ). The backtick (的多行字符串). The backtick ( ). The backtick ( )—which is not the same character as a single quote (')—allows you to compose a string over several lines, which makes the HTML more readable. ). The backtick ( ）与单引号（'）不同，它使您可以在多行上组成一个字符串，从而使HTML更具可读性。

import { Component } from '@angular/core';

    @Component({
      selector: 'pm-root',
      template: `<div><h1>{{pageTitle}}</h1></div>` // **added backticks**  
    })
    export class AppComponent {
      pageTitle: string = 'Angular: Getting Started';
    }
