我正在运行一个有角度、放大和认知的应用程序。当我ng serve运行应用程序时出现此错误。我尝试删除所有节点模块 package-lock.json 但它没有改变任何东西所以我想知道我应该改变什么以使其在执行 ng serve 时正常工作。

ERROR in node_modules/amazon-cognito-identity-js/index.d.ts:1:1

该amazon-cognito-identity-js软件包不是必需的，并且是aws-amplify.

My modules:
    "@angular/animations": "~11.0.5",
    "@angular/cdk": "^11.0.3",
    "@angular/common": "~11.0.5",
    "@angular/compiler": "~11.0.5",
    "@angular/core": "~11.0.5",
    "@angular/forms": "~11.0.5",
    "@angular/material": "^11.0.3",
    "@angular/platform-browser": "~11.0.5",
    "@angular/platform-browser-dynamic": "~11.0.5",
    "@angular/router": "~11.0.5",
    "@aws-amplify/ui-angular": "^0.4.17-unstable.1",
    "@types/graphql": "^14.5.0",
    "angular-gridster2": "^10.1.7",
    "aws-amplify": "^3.3.14-unstable.1",

    "node-fetch": "^2.6.1",
    "rxjs": "~6.6.0",
    "tslib": "^2.0.0",
    "zone.js": "~0.10.2"

write in polyfilss.ts:
(window as any).global = window;

directly into package.json:
  "browser": {
    "crypto": false
  }

app-module aws-imports:
import Amplify from 'aws-amplify';
import {AmplifyUIAngularModule} from '@aws-amplify/ui-angular';
import awsmobile from '../aws-exports.js';

Amplify.configure(awsmobile);

在 .../build/options 下的 angular.json 中：

          "@aws-amplify/ui-components",
          "isomorphic-unfetch"
        ]

在 tsconfig.json 作为 compilerOptions 的一部分：

"paths": {
  "crypto": [
    "../../node_modules/crypto-js"
  ]
}

那么就没有更多的警告或错误了。
