我將一個項目從 Angular 7 遷移到 Angular 8，我不得不將 Renderer 類更改為 Renderer2，我面臨以下錯誤：ERROR Error: Template error: Can't bind to 'disabled' since it isn't a known property of 'div'.    at createUnknownPropertyError (vendor.js:83083)    at validateAgainstUnknownProperties (core.js:12699)    at elementPropertyInternal (core.js:12604)    ...渲染器的課程如何：import { OnInit, Directive, Input, Renderer, ElementRef } from '@angular/core';import { Observable } from 'rxjs/Observable';import { Response } from '@angular/http';import { Loader } from './loader';@Directive({    selector: '[asCardLoader]'})export class CardDirective implements OnInit {    private nativeElement: Node;    private loaderElement: Node;    constructor(private renderer: Renderer, private element: ElementRef) {        this.nativeElement = element.nativeElement;    }    ngOnInit() {        if (this.loader) {            this.initLoader();        }    showLoading() {        const divElement = this.renderer.createElement(this.nativeElement, 'div');        this.renderer.setElementClass(divElement, 'card-loading', true);        this.renderer.setElementStyle(divElement, 'display', 'block');        this.loaderElement = divElement;        const nextElem = this.element.nativeElement.nextElementSibling;        const parent = this.element.nativeElement.parentNode;        parent.insertBefore(divElement, nextElem);// other methods我對 renderer2 的嘗試import { OnInit, Directive, Input, Renderer2, ElementRef } from '@angular/core';import { Observable } from 'rxjs/Observable';import { Response } from '@angular/http';import { Loader } from './loader';@Directive({    selector: '[asCardLoader]'})對于 renderer2，creatElement 方法盡管具有相同的名稱，但不再以相同的方式工作，而且我從文檔中不能很好地理解應該進行這種轉換的正確方式。
