Transitioning from angular 7 to the latest version 12

Upgrading from Angular 7 to 12 has presented a series of issues for me.

The main problem seems to be with Angular Material.

I am looking for a solution to this.

./src/app/material.module.ts:13:89-110 - Encounter Error: 'MatAutocompleteModule' (imported as 'MatAutocompleteModule') not found in '@angular/material'

./src/app/material.module.ts:13:112-126 - Encountered Error: 'MatBadgeModule' (imported as 'MatBadgeModule') was not found in '@angular/material'

./src/app/material.module.ts:13:128-148 - Encountered Error: 'MatBottomSheetModule' (imported as 'MatBottomSheetModule') not found in '@angular/material'

... and so on
angulartypescript

Answer №1

Starting from Angular Material version 9, each module must be imported from its own unique path. For example:

import { MatAutocompleteModule } from '@angular/material/autocomplete';

If you have updated your Angular application using the ng update command (it is advised to use this method for updating Angular, although it is not recommended to skip multiple major versions, see here for more information), the migration process will automatically take care of updating the imports and no manual changes are required.
