node.js - aws-sdk/clients/cognitoidentity 没有导出成员 'String'

Question

启动 Angular 6.1.2 项目时出现此错误:

ERROR in node_modules/aws-amplify-angular/lib/components/storage/photo-picker-component/photo-picker.factory.d.ts(3,10): error TS2305: Module '"/Users/knewtone/Dropbox/knewtone.com/projects/WorkSpace/softwares/yet.marketing/node_modules/aws-sdk/clients/cognitoidentity"' has no exported member 'String'.

更新

我在文件中看到错误

node_modules/aws-amplify-angular/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;
}

然后我更换了

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

与

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

并且没有错误!

这是一个已知问题并已解决 upstream .

对于遇到此问题的任何人，只需将您的 aws-amplify 版本至少更新到 1.1.x 并将 aws-amplify-angular 更新到版本 2.0.x。
