Amplify-js: No Auth module registered in Amplify

[aldarund]

Describe the bug
A clear and concise description of what the bug is.
"@aws-amplify/core": "1.0.17"
"@aws-amplify/auth": "1.2.9",
"@aws-amplify/api": "1.0.20", - work fine

updating either of the package to next version give this error

No Auth module registered in Amplify

To Reproduce
In one place i have

  Amplify.configure({
      Auth: config
    });

In other i have

  Amplify.register(API)

  const aws_config = {
    aws_appsync_graphqlEndpoint: process.env.APPSYNC_ENDPOINT,
    aws_appsync_region: process.env.AWS_REGION,
    aws_appsync_authenticationType: 'AMAZON_COGNITO_USER_POOLS',
    endpoints: [
      {
        name: 'RequestLogin',
        endpoint: process.env.REQUEST_LOGIN_ENDPOINT
      }
    ]
  }

  inject('amplifyApi', API)

  Amplify.API.configure(aws_config)

Expected behavior
No Auth module registered in Amplify error
Work fine in previous version of amplify ( "@aws-amplify/api": "1.0.20" ) so its regression

Additional context
Might be same or related to https://github.com/aws-amplify/amplify-js/issues/2058 but i dont use storage.

You can turn on the debug mode to provide more info for us by setting window.LOG_LEVEL = 'DEBUG'; in your app.

@aldarund Hi how are you importing those modules(Auth, API, Amplify) in your code? It usually happens when you didn't import the Auth module in your code.

[aldarund]

@powerful23 I`m importing it (once in code)

import Auth from '@aws-amplify/auth'
import Amplify from '@aws-amplify/core'

And as i said it is working with previous release fine. No code change - just change version and will go from working to not working.

[aldarund]

its because package manager create individual copy of core/auth/api libs for each of core/auth/api packages.

And it happened because of lock file that was having older versions. Deleting lock file and recreating fixes the issue

Thanks @aldarund !!!! I did an npm update, deleted the folder @aws-amplify from node_modules folder, and then did a npm install. After doing that, it worked.
