尝试使用ionic cordova build android --prod --release或使用ionic serve或ionic cordova run android应用程序效果很好。
错误：c：/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.t.ts中键入pdfviewercomponent，是2个模块声明的一部分：c：/app/node_modules/ng2-2-2--pdf-viewer/ng2-pdf-viewer.d.t.ts和pdfmodalpagemodule中的c：/app/src/pages/document-pdf/document-pdf/document-pdf.module.ts！请考虑在c：/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.t.ts中移动pdfviewercompongent，以在c：/app/nonode_modules/ng2-pdf-viewer/ng2-viewer/ng2-ng2-ng2-ng2-ng2-ng2-ng2--pdf-viewer.d.t.ts和pdfmodalpagemodule中的c：/app/src/pages/document-pdf/document-pdf.module.ts。您还可以创建一个新的ngmodule，该新ngmodule在c：/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts中导入pdfviewercomponent.d.t.t.-pdf-viewer/ng2-pdf-viewer.d.ts和pdfmodalpagemodule in c：/app/src/pages/document-pdf/document-pdf/document-pdf.module.ts。
我仅在 document-pdf.module.ts中导入ng-pdf-viewer，而不是在app.module.ts
import {NgModule} from '@angular/core';
import {IonicPageModule} from 'ionic-angular';
import {PdfModalPage} from "./document-pdf";
import {PdfViewerComponent} from "ng2-pdf-viewer";
@NgModule({
declarations: [PdfModalPage, PdfViewerComponent],
imports: [IonicPageModule.forChild(PdfModalPage)],
})
export class PdfModalPageModule {}

我尝试使用新的安装删除/平台/www/插件和/node_modules
您应该在document-pdf.module.ts中导入PdfViewerModule，并且不在其中声明PdfViewerComponent，因为它已经在PdfViewerModule中声明。
更新：这就是您的模块的外观：
import {NgModule} from '@angular/core';
import {IonicPageModule} from 'ionic-angular';
import {PdfModalPage} from "./document-pdf";
import { PdfViewerModule } from 'ng2-pdf-viewer';
@NgModule({
declarations: [PdfModalPage],
imports: [IonicPageModule.forChild(PdfModalPage), PdfViewerModule]
})
export class PdfModalPageModule {}
