angular - 类型错误 : Cannot read property 'toString' of undefined Angular 6

Question

我正在尝试使用 angular 6 构建一个库，但我遇到了一些问题。

在将 --SoumissionStructComponent-- 添加到我的库模块之前没有发生任何错误

但是一旦我添加它，我就得到了这个

TypeError: Cannot read property 'toString' of undefined
 at new Input (C:\Users\taha.manar\Documents\workspace\Adjucation-Ihm\node_modules\ng-packagr\node_modules\postcss\lib\input.js:53:20)
 at parse (C:\Users\taha.manar\Documents\workspace\Adjucation-Ihm\node_modules\ng-packagr\node_modules\postcss\lib\parse.js:13:15)

 at Processor.<anonymous> (C:\Users\taha.manar\Documents\workspace\Adjucation-Ihm\node_modules\ng-packagr\node_modules\postcss\lib\processor.js:138:12)
...

SoumissionStructComponent.ts

import { Component, OnInit } from '@angular/core';
import { SoumissionService } from './soumission.service';
import { ListElements, ElementList } from './../Common/root-page/model/ElementList';

@Component({
  selector: 'app-soumission-struct',
  templateUrl: './soumission-struct.component.html',
  styleUrls: ['./soumission-struct.component.css']
})
export class SoumissionStructComponent implements OnInit {
  listElements: ListElements;
  elementsList: ElementList[] = [];
  constructor(private soumissionService: SoumissionService) {
soumissionService.getActivatedSoumission().subscribe((r: any) => {

  this.listElements = new ListElements();
  this.listElements.listElts = [];
  if (r) {
    this.listElements.listElts.push({ key: r.id, value: r.seanceDate });
  }
});
  }

  ngOnInit() {
  }

}

希望我已经把问题描述清楚了

在 ng generate 之后，你是否更改了你的 css -> scss？如果是这样，那么您需要更新 styleUrls。
