在--prod build中使用ng2- libraries抛出“意想不到的值...请添加@管道/@指令/@组件注释”

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'myPipe',
  pure: false
})
export class MyPipe implements PipeTransform {
  transform(value: any, args?: any): any {
    // 管道的转换逻辑
    return transformedValue;
  }
}

import { Directive, ElementRef } from '@angular/core';

@Directive({
  selector: '[myDirective]'
})
export class MyDirective {
  constructor(private elementRef: ElementRef) {
    // 指令的逻辑
  }
}

import { Component } from '@angular/core';

@Component({
  selector: 'my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent {
  // 组件的属性和方法
}
