React Native AWS Amplify AuthError：Amplify 尚未正确配置

Question

我在我的 React Native 项目中使用 AWS Amplify 库并手动配置登录。我可以使用 React Native 项目登录 Android 应用程序，但是当我在 ios 中运行相同的 React Native 代码时，我得到了以下错误。我正在从 React Native 中的 .env 文件中获取放大配置参数数据。

我已按照以下步骤进行 iOS pod 安装来设置 Amplify 库 https://docs.amplify.aws/lib/auth/start/q/platform/js#configure-your-application

我已经在 iOS 中安装了与https://www.npmjs.com/package/react-native-config和 amplify 库相关的所有 pod 。

// import Amplify, { Auth } from 'aws-amplify';
   import Amplify from '@aws-amplify/core';
   import Auth from '@aws-amplify/auth';

  /** Configration of Cognito Auth Process for mobile client */
    Amplify.configure({
      Auth: {

  // REQUIRED only for Federated Authentication - Amazon Cognito Identity Pool ID
  identityPoolId: Config.REACT_APP_AWS_COGNITO_IDENTITY_POOL_ID,

  // REQUIRED - Amazon Cognito Region
  region:  Config.REACT_APP_AWS_COGNITO_REGION,

  // OPTIONAL - Amazon Cognito User Pool ID
  userPoolId: Config.REACT_APP_AWS_COGNITO_USER_POOL_ID,

  // OPTIONAL - Amazon Cognito Web Client ID (26-char alphanumeric string)
  userPoolWebClientId: Config.REACT_APP_AWS_COGNITO_USER_POOL_WEB_CLIENT_ID,

  // OPTIONAL - Enforce user authentication prior to accessing AWS resources or not
  mandatorySignIn: false,

  // OPTIONAL - Manually set the authentication flow type. Default is 'USER_SRP_AUTH'
  authenticationFlowType: 'USER_PASSWORD_AUTH',

   // OPTIONAL - Hosted UI configuration
  oauth: {
      domain: Config.REACT_APP_AWS_COGNITO_OAUTH_DOMAIN,
      scope: ['openid', 'aws.cognito.signin.user.admin'],
      redirectSignIn: Config.REACT_APP_AWS_COGNITO_OAUTH_REDIRECT_SIGNIN,
      redirectSignOut: Config.REACT_APP_AWS_COGNITO_OAUTH_REDIRECT_SIGNOUT,
      responseType: Config.REACT_APP_AWS_COGNITO_OAUTH_RESPONSE_TYPE, // or 'token', note 
      that REFRESH token will only be generated when the responseType is code
     }
     }.   
   });

   // You can get the current config object
    const currentConfig = Auth.configure();

  //Usage
   Auth.signIn(username, password).then(
    (result) => {
      console.log(result);
      if(result instanceof CognitoUser){
        console.log(result.getSignInUserSession()?.getAccessToken().getJwtToken());
        console.log(result.getSignInUserSession()?.getIdToken());
        console.log(result.getSignInUserSession()?.getRefreshToken());
      }
      this.props.navigation.replace('ChangePassword');
    }
  ).catch(
    (error) => {
      console.log('################# SignIn Error :');
      console.log(error);
    }
  )
   } catch (exception) {
  console.log(exception);
     console.log('################# Exception in SignIn API call');
    }

无法弄清楚出了什么问题。

 [ERROR] 27:54.153 AuthError - 
        Error: Amplify has not been configured correctly. 
        The configuration object is missing required auth properties. 
        Did you run `amplify push` after adding auth via `amplify add auth`?
        See https://aws-amplify.github.io/docs/js/authentication#amplify-project-setup for 
   more information

请告诉我为什么当我在 iOS 中运行时上面的代码显示错误。

更新 Amplify 版本后，我遇到了同样的问题。我删除了node_modues文件夹和package-lock.json。我运行了“npm install”并修复了它。
