我试图在我当前的项目中启用angularivy,而在ng构建时,我遇到了这个错误

我检查了一些建议,比如在导出中创建函数并再次使用它来解决问题,但错误并没有得到解决,反而发生了变化

  ],
  exports: [],
  entryComponents: [],
  providers: [
    AuthGuard, 
    { provide: LOCALE_ID, useValue: 'es' },
    CommonService, 
    {
      provide: NgbDateParserFormatter,
      useFactory: () => new CustomNgbDateParserFormatter('longDate')
    },

如果错误得到解决

()=>{}
替换为
function(){}
会有帮助。

在声明模块之前,请尝试这样导出函数

export function createCustomFormatter(): Function
{
  return () => new CustomNgbDateParserFormatter('longDate');
}
然后在提供程序中使用该函数

providers: [
  CommonService, 
  {
    provide: NgbDateParserFormatter,
    useFactory: createCustomFormatter
  },

    provide: NgbDateParserFormatter,

嘿,我有:useFactory:()=>新的CustomNgbDateParserFormatter('longDate')您是否建议将其转换为以下格式?useFactory:function(){return new CustomNgbDateParserFormatter('longDate');}请@user3875919,让我知道是的,让我们试试。对不起,我正忙于其他任务,现在它不需要了,但谢谢你的建议。嘿,我有:useFactory:()=>new CustomNgbDateParserFormatter('longDate')你建议将它转换为如下格式吗?useFactory:function(){return new CustomNgbDateParserFormatter('longDate');}请@user3875919,让我知道是的,让我们试试。对不起,我正忙于其他任务,现在不需要了,但谢谢你的建议。对不起,我正忙于其他任务,现在不需要了,但谢谢你的建议,现在不需要了,但是谢谢你的建议。
