使用globalize的Angular CLI生产性构建错误

Question

我正在尝试使用全球化本地化角度6 + 应用程序。

它可以在开发模式下构建并正常工作，但是不幸的是，将其构建为生产模式：“ ng build --prod ”我收到此错误：“ 无法读取属性'Symbol中的错误（Symbol.iterator）'未定义”。

本地化的源代码编写在名为“ german-language.service.ts ”的服务中。如果我注释掉“ initLagnuage ”方法的内容，则它将正确构建。

全球化并安装devextreme-cldr-data。还尝试了cldr-data。

有人和想法如何解决该问题吗？

编辑：

如果在tsconfig.json中注释掉“ resolveJsonModule：true”，则不会出现该错误。

似乎与角度错误有关：使用AOT＃25456进行编译时，TypeScript resolveJsonModule功能已损坏

german-language.service.ts

import { Injectable } from '@angular/core';
import deMessages from 'devextreme/localization/messages/de.json';
import Globalize from 'globalize';
import 'devextreme/localization/globalize/number';
import 'devextreme/localization/globalize/date';
import 'devextreme/localization/globalize/currency';
import 'devextreme/localization/globalize/message';
import deCldrData from 'devextreme-cldr-data/de.json';
import supplementalCldrData from 'devextreme-cldr-data/supplemental.json';

@Injectable({
  providedIn: 'root'
})
export class GermanLanguageService {

  constructor() { }

  initLanguage() {
    Globalize.load(
      deCldrData,
      supplementalCldrData
    );
    Globalize.loadMessages(deMessages);
    Globalize.locale('de');
  }
}

应用程序配置如下：
