If you remove directives attribute it should work.

@Component({
    selector: 'parent',
    template: `
            
Parent Component
            
        `
    })
    export class ParentComponent{}


@Component({
    selector: 'child',    
    template: `
            
Child Component
        `
    })
    export class ChildComponent{}

Directives are like components but they are used in attributes. They also have a declarator @Directive. You can read more about directives Structural Directives and Attribute Directives.

There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.

A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.

Also if you are open the glossary you can find that components are also directives.

Directives fall into one of the following categories:

• Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.

• Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.

• Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.

The difference that components have a template. See Angular Architecture overview.

A directive is a class with a @Directive decorator. A component is a directive-with-a-template; a @Component decorator is actually a @Directive decorator extended with template-oriented features.

The @Component metadata doesn't have directives attribute. See Component decorator.
