Amplify-js: Vue.js + TypeScript build error, `Could not find a declaration file for module '@aws-amplify/ui'`

[yukitaka13-1110]

Vue.js + TypeScript + AWS Amplify, I encountered the following error.
Could not find types file.
Is this error default behavior ?
Is there a way to avoid this error?

@yukitaka13-1110 Can you upgrade to the latest versions of aws-amplify-vue and @aws-amplify/ui. Prior to upgrading, please delete your node_modules along with a lock file (e.g. package-lock.json or yarn.lock) and see if you're still experiencing this issue.

[yukitaka13-1110]

Thank you for quick response.
I tried this way.

$ npm uninstall aws-amplify-vue --save
$ 

I could resolve about @aws-amplify, but I still get this error in aws-amplify-vue.

ERROR in /mypath/src/main.ts
9:31 Could not find a declaration file for module 'aws-amplify-vue'. 
'/mypath/node_modules/aws-amplify-vue/dist/aws-amplify-vue.common.js' 
implicitly has an 'any' type.
  Try `npm install @types/aws-amplify-vue`
 if it exists or add a new declaration (.d.ts) file containing `declare module 'aws-amplify-vue';`

     8 | import Amplify, * as AmplifyModules from 'aws-amplify'
  >  9 | import { AmplifyPlugin } from 'aws-amplify-vue'
       |                               ^
    10 | import awsexports from './aws-exports'
    11 |
    12 | Vue.config.productionTip = false

Dose types folder exist in aws-amplify-vue ?

@yukitaka13-1110 Apologize for not explaining it further but really the steps below would be how I (myself) would go about upgrading when using yarn.

This removes any node module issues that may still be living in the lock file.
rm -rf node_modules yarn.lock
Installing dependencies will, which in turn adds the latest versions.
yarn

However, to your point, we don't currently have typing available in our Vue library. I am going to mark this as a feature request since this isnt something we have added yet.

+1 to typing definitions.
