Currently, I upgrade my Angular project form 8 to 9. 
The project's using a "@types/moment-timezone": "^0.5.30" in package.json 
Now this package has been deprecated. https://www.npmjs.com/package/@types/moment-timezone 
When I run the project ng serve, it shows up this error message
user.model.ts:3:25 - error TS7016: Could not find a declaration file for module 'moment-timezone'. '/home/bunthai/sftp/upgrade/projectg/ui/ctr/node_modules/moment-timezone/index.js' implicitly has an 'any' type.
  Try `npm install @types/moment-timezone` if it exists or add a new declaration (.d.ts) file containing `declare module 'moment-timezone';`
import * as moment from 'moment-timezone';
                          ~~~~~~~~~~~~~~~~~
How to deal with this problem?
