Angular 无法声明';TimeAgoPipe';在一个NGO模块中,因为它';这不是当前汇编的一部分

Angular 无法声明';TimeAgoPipe';在一个NGO模块中,因为它';这不是当前汇编的一部分,angular,ng-modules,Angular,Ng Modules,在执行ng build--prod时,Angular 10中出现错误。它在ng build中工作 ERROR in src/app/app.module.ts:44:5 - error NG6001: Cannot declare 'TimeAgoPipe' in an NgModule as it's not a part of the current compilation. 44 TimeAgoPipe, ~~~~~~~~~~~ node_modules/ti

在执行
ng build--prod
时,
Angular 10
中出现错误。它在
ng build
中工作

ERROR in src/app/app.module.ts:44:5 - error NG6001: Cannot declare 'TimeAgoPipe' in an NgModule as it's not a part of the current compilation.

44     TimeAgoPipe,
       ~~~~~~~~~~~

  node_modules/time-ago-pipe/time-ago.pipe.d.ts:3:22
    3 export declare class TimeAgoPipe implements PipeTransform, OnDestroy {
                           ~~~~~~~~~~~

这是
node\u模块/time-ago管道/time-ago.pipe.d.ts中的文件

import { PipeTransform, NgZone, ChangeDetectorRef, OnDestroy } from "@angular/core";
import * as ɵngcc0 from '@angular/core';
export declare class TimeAgoPipe implements PipeTransform, OnDestroy {
    private changeDetectorRef;
    private ngZone;
    private timer;
    constructor(changeDetectorRef: ChangeDetectorRef, ngZone: NgZone);
    transform(value: string): string;
    ngOnDestroy(): void;
    private removeTimer();
    private getSecondsUntilUpdate(seconds);
    static ɵfac: ɵngcc0.ɵɵFactoryDef<TimeAgoPipe, never>;
    static ɵpipe: ɵngcc0.ɵɵPipeDefWithMeta<TimeAgoPipe, "timeAgo">;
}

如何修复此问题?

TimeAgoPipe
添加到
导出
应用程序模块的数组中。

此软件包已三年未维护,我建议使用,您可以在此处找到有关此问题的更多详细信息

这个解决方案对一些人有效

...
import { TimeAgoPipe } from 'time-ago-pipe';

@Pipe({
    name: 'timeAgo',
    pure: false
})
export class TimeAgoExtendsPipe extends TimeAgoPipe {}

@NgModule({
    declarations: [
        TimeAgoExtendsPipe,
...

app.module.ts
中,似乎没有
export
数组。您可以像
imports
一样添加
exports
数组。尝试了此操作,但出现了相同的错误
exports:[TimeAgoPipe],
...
import { TimeAgoPipe } from 'time-ago-pipe';

@Pipe({
    name: 'timeAgo',
    pure: false
})
export class TimeAgoExtendsPipe extends TimeAgoPipe {}

@NgModule({
    declarations: [
        TimeAgoExtendsPipe,
...
