aws sdk/clients/cognitoidentity没有导出的成员“String”

当启动角度6.1.2项目时,我有一个错误:

错误 节点模块/aws放大角度/lib/components/storage/photo picker component/photo picker.factory.d.ts(3,10): 错误TS2305:模块 “/Users/knewtone/Dropbox/knewtone.com/projects/WorkSpace/softwares/yet.marketing/node_modules/aws sdk/clients/cognitoidentity”” 没有导出的成员“String”。

更新

我看到文件中的错误

节点模块/aws放大角度/lib/components/storage/photo picker component/photo picker.factory.d.ts

import { OnInit, ComponentFactoryResolver, OnDestroy, EventEmitter } from '@angular/core';
import { DynamicComponentDirective } from '../../../directives/dynamic.component.directive';
import * as String from 'aws-sdk/clients/cognitoidentity'; // <--- the replaced statement

export declare class PhotoPickerComponent implements OnInit, OnDestroy {
  private componentFactoryResolver;
  framework: String;
  url: string;
  picked: EventEmitter<string>;
  loaded: EventEmitter<string>;
  componentHost: DynamicComponentDirective;
  constructor(componentFactoryResolver: ComponentFactoryResolver);
  ngOnInit(): void;
  ngOnDestroy(): void;
  loadComponent(): void;
}

然后我换了

import { String } from 'aws-sdk/clients/cognitoidentity';

具有

import * as String from 'aws-sdk/clients/cognitoidentity';

没有错误!
