找不到t的零件工厂您是否将其添加到@ NgModule.entryComponents?

问题描述

我创建了一个组件来本地预览项目中的docx和pdf文件(角度6)。要预览pdf,我使用了ng2-pdf-viewer并预览了docx,docx文件在后端被转换为html,发送到角度。 docx和pdf的预览在本地计算机上工作正常,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”。我认为没有这样的组成部分。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>
