angular - 未找到 t 的组件工厂。你把它添加到@NgModule.entryComponents 了吗？

Question

我已经创建了一个组件来在我的项目中本地预览 docx 和 pdf 文件（角度 6）。要预览 pdf，我使用了 ng2-pdf-viewer并预览 docx，docx 文件在后端转换为 html 并发送到 angular . docx 和 pdf 的预览在本地机器上工作正常，但在服务器上不起作用。控制台中的错误如下所示。在错误中它提到了组件“t”。我不认为有这样的组件。这可能是另一个错误。

.html 文件：

<loading-spinner *ngIf="loading"></loading-spinner>
<div *ngIf="!loading">
<!-- for pdf  -->
<pdf-viewer *ngIf="isPdf" [src]="pdfSrc" style="display: block;" (after-load-complete)="afterLoading()"
 (error)="onError()" (contextmenu)="onRightClick()" [zoom]="zoom">
</pdf-viewer>
<!-- for docx  -->
<div class="container" *ngIf="isDocx">
 <div [innerHTML]="html" class="doc" (contextmenu)="onRightClick()" (click)="onLeftClick()"></div>
</div>

</div>


<button class="btn btn-light zoomIn" (click)="zoomIn()"><i class="fa fa-search-plus" aria-hidden="true"></i></button>
<button class="btn btn-light zoomOut" (click)="zoomOut()"><i class="fa fa-search-minus" aria-hidden="true"></i></button>

ts文件：

import { Component, OnInit, Directive, ElementRef, Renderer2 } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
import { environment } from '../../../environments/environment';
import { PublicService } from '../public.service';
declare var jQuery: any;

@Component({
  selector: 'app-file-preview',
  templateUrl: './file-preview.component.html',
  styleUrls: ['./file-preview.component.css']
})

@Directive({ selector: '[preventCutCopyPaste]' })

export class FilePreviewComponent implements OnInit {

  fileName;
  siteUrl = environment.resourcecUrl + "/";
  doc;
  loading = true;
  isPdf = false;
  isDocx = false;
  html;
  pdfSrc;
  zoom = 1;

  constructor(
    private route: ActivatedRoute,
    public publicService: PublicService,
    el: ElementRef, renderer: Renderer2
  ) {
    this.route.queryParams.subscribe(params => {
      this.fileName = params['fileName'];
      this.pdfSrc = this.siteUrl + "upload/project/" + this.fileName;
      this.checkFileType();
    });
    //disable copy
    var events = 'cut copy paste';
    events.split(' ').forEach(e =>
      renderer.listen(el.nativeElement, e, (event) => {
        event.preventDefault();
      })
    );
  }

  ngOnInit() {

  }

  zoomIn() {
    this.zoom += 0.1;
    console.log(this.zoom);
  }
  zoomOut() {
    this.zoom -= 0.1;
    console.log(this.zoom);
  }


  checkFileType() {
    const res = this.fileName.split('.');
    const fileType = res[res.length - 1];
    if (fileType == 'pdf') {
      this.isPdf = true;
    } else if (fileType == 'docx') {
      this.isDocx = true;
      this.publicService.docx2html(this.fileName).subscribe(
        response => {
          this.html = response;
          // console.log(response);
          this.loading = false;
        })
    } else {
      this.onError();
    }
  }

  onRightClick() {
    return false;
  }
  onLeftClick() {
    return false;
  }

  afterLoading() {
    this.loading = false;
  }

  onError() {
    alert("Cannot load file");
  }

}
