我正在使用Angular 5中的模式库，该库中的组件之一是jquery数据表。模式库是应用程序的一部分，该应用程序包含一些有关如何使用组件的演示页面，并且jquery数据表在该应用程序中可以正常工作。当我将组件打包/导出到另一个应用程序时，导航到使用该组件的页面时出现以下错误：
Error: Uncaught (in promise): TypeError: table.DataTable is not a function
AOT编译器未捕获此错误。
使用this article并进行一些调试，我确定问题是该组件在使用ng-packagr打包时没有正确导入jquery数据表依赖项，即使该依赖项是安装在导入库的应用程序的node_modules中。
这是数据表组件：
import { HttpClient } from '@angular/common/http';
import { Component, OnInit, ChangeDetectorRef, Input, Output, EventEmitter, ContentChild, TemplateRef } from '@angular/core';
import { Subscription } from 'rxjs/Subscription';
import * as jquery from 'jquery';
const $: JQueryStatic = (<any>jquery).default || jquery;
import 'datatables.net';
import 'datatables.net-bs4';
import 'datatables.net-select';
import 'datatables.net-buttons';
import 'datatables.net-buttons/js/buttons.colVis.js';
import 'datatables.net-select-dt';
import { PARAMETERS } from '@angular/core/src/util/decorators';
@Component({
selector: 'lib-datatable',
templateUrl: './datatable.component.html'
})
export class DataTableComponent implements OnInit {
data: any[];
dataTable: any;
allSelected = false;
...
...
...
constructor(private http: HttpClient, private chRef: ChangeDetectorRef) {}
ngOnInit() {
Function.call(this.dataFunction(this.dataParams).then((data: any[]) => {
this.data = data;
const table: any = $('#' + this.tableId);
this.prepareBulkActionBtns();
// this.tableSettings.buttons.push(this.manageColsBtn);
this.prepareColDefs();
this.tableSettings.data = data;
this.dataTable = table.DataTable(this.tableSettings);
this.dataTable.on( 'select deselect', function ( e, dt, type, indexes ) {
const selectedRows = dt.rows( { selected: true } ).count();
dt.button('.bulkAction').enable( selectedRows > 0 );
} );
$('.ellipsis-menu').off('click').on('click', function(event) {
if ($('[aria-labelledby="' + $(this).data('id') + '"]').css('display') === 'none') {
$('.row-menu').css('display', 'none');
$('[aria-labelledby="' + $(this).data('id') + '"]').css('display', 'block');
} else {
$('[aria-labelledby="' + $(this).data('id') + '"]').css('display', 'none');
}
});
const component = this;
$('.row-action').off('click').on('click', function() {
const id = $(this).data('id');
const action = $(this).data('action');
$('.row-menu').css('display', 'none');
component.selectRowAction(action, id);
});
}));
}
...
...
...

为什么组件无法在原型应用程序中找到数据表依赖关系，但可以找到jquery依赖关系？是否可以声明多个jquery实例？我不这么认为，但也许其他人可以确定是否是这种情况。
如何获取数据表组件以始终能够找到jquery数据表依赖关系，无论它是在模式库中还是在导入模式库组件的原型中？
