样式未应用于渲染的组件[关闭]

In the issue #32179 https://github.com/angular/angular/issues/32179 , there is an answer about rendering a component with styles, but I didn't get it.

与常春藤一起运行Angular 9

我的示例代码：

import {
    ɵrenderComponent as renderComponent,
    ɵdetectChanges as detectChanges,
    ɵLifecycleHooksFeature as LifecycleHooksFeature,
    Injector
  } from '@angular/core';
....
    async renderComponent() {
      const { HelloWorldComponent } = await import('./hello-world.component');
      this.component = renderComponent(HelloWorldComponent, { 
        host: this,
        **rendererFactory: Didn't know what to do here.**
        hostFeatures: [
          LifecycleHooksFeature,
        ],
        injector: this.injector
      });
      this.component.text = this.text;
      detectChanges(this.component);
    }
