node.js - global.util.crypto.lib.randomBytes 不是函数错误

Question

我是新手。使用 amazon-cognito-identity-js 时出错时出现以下错误npm 包如下所示

_global.util.crypto.lib.randomBytes is not a function

我在react中的Actions文件如下

    import axios from 'axios';
    import * as actionTypes from './actionTypes';
    import authenticateUser from '../services/cognitoAuthenticateUser';
    import {reset} from 'redux-form';


    const signInUserSuccess = ({...result,email, newPasswordRequired = false}) => {
      return {
        type: actionTypes.SIGNIN_SUCCESS,
        ...result,
        email
      }
    };

    const signInUserFailure = (error) => {
      return {
        type: actionTypes.SIGNIN_FAILURE,
        error
      }
    };


    /* Login a given user based on his credentials added */
    export function LoginFeature(email,password,callback){

      return (dispatch) => {
        authenticateUser(email, password)
         .then(result => {
                          //console.log(result);
                          dispatch(signInUserSuccess({...result, email}));
                          callback();
                          dispatch(reset('loginForm'));
                          })
         .catch(e => {
           dispatch(signInUserFailure(e.message));
           dispatch(reset('loginForm'));
         })
      }
    }

我的User Authenticate service文件如下

import {
    AuthenticationDetails,
    CognitoUserPool,
    CognitoUser} from "amazon-cognito-identity-js";

  import {Config} from "aws-sdk";


  import awsConfig from "../../configs/aws-incognito-credentials";

  /*Credentails for AWS Incognito usage*/
  Config.region = awsConfig.region;

  const userPool = new CognitoUserPool({
    UserPoolId: awsConfig.UserPoolId,
    ClientId: awsConfig.ClientId
  });

  // Use case 4. Authenticating a user and establishing a user session with the Amazon Cognito Identity service.
  export const authenticateTheGivenUser = (username, password) => {
    return new Promise(function (resolve, reject) {

      const user = new CognitoUser({ Username: username, Pool: userPool })
      const authenticationData = { Username: username, Password: password }
      const authenticationDetails = new AuthenticationDetails(authenticationData)

      user.authenticateUser(authenticationDetails, {
        onSuccess: result => {
          console.log(result);
          resolve({...result, newPasswordRequired: false})
        },
        onFailure: err => reject(err),
        newPasswordRequired: (userAttributes, requiredAttributes) => resolve({newPasswordRequired: true})
      })
    })
  }

  export default authenticateTheGivenUser;

我的package.json文件如下

 "devDependencies": {
  "babel-core": "^6.2.1",
  "babel-loader": "^6.2.0",
  "babel-preset-es2015": "^6.1.18",

  "react-toastify": "^3.2.1",
  "redux": "^3.0.4",

}

我无法理解为什么会出现此错误？有人可以指出我做错了什么吗？

降级 aws-sdk 解决了这个问题:

yarn add aws-sdk@2.177.0

对我来说，aws-sdk 是 aws-amplify 的依赖项，并且会自动更新，之后我开始看到同样的错误。
