Some Material Modules not working after v9 update

[nejat-njonjo]

Regression

I updated my project to version 9 of angular and I updated Angular material as well. Before the update everything was working fine, but after the update, the following Angular Material Modules are not working.
MatBottomSheetModule
MatSnackBarModule

The following are working but tslint shows the modules do not have exported members.
MatChipsModule
MatAutocompleteModule

Here is my customized material module

import { MatButtonModule } from '@angular/material/button';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatInputModule } from '@angular/material/input';
import { MatSelectModule } from '@angular/material/select';
import { MatSnackBarModule } from '@angular/material/snack-bar';
import { MatChipsModule } from '@angular/material/chips';
import { MatIconModule } from '@angular/material/icon';
import { MatAutocompleteModule } from '@angular/material/autocomplete';
import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatBottomSheetModule } from '@angular/material/bottom-sheet';

Expected Behavior

All modules should have exported members

Actual Behavior

Module 'node_modules/@angular/material/snack-bar' has no exported member 'MatSnackBarModule'.

Module 'node_modules/@angular/material/chips' has no exported member 'MatChipsModule'.

Module 'node_modules/@angular/material/bottom-sheet"' has no exported member 'MatBottomSheetModule'.

Module 'node_modules/@angular/material/autocomplete' has no exported member 'MatAutocompleteModule'.

Environment

• Angular: 9.0.1
• Node Version: 12.13.1
• CDK/Material: 9.0.0
• Browser: Chrome, Opera, Mozilla
• Operating System: Windows 10, x64

Can anyone share a reproduction? We aren't able to reproduce this in any of our environments.

I got the same issue and fixed it.

In my Visual Studio Code, some modules was not found even they was in my node_modules.

What I did to fix:

1. Deleted my node_modules directory.
2. Installed NPM package: npm install
3. Restarted Visual Studio Code.
4. Issue gone!

Good old rm -rf thanks, brother!

note: I'm using Angular 8....

Going to close this then, since it seems like it was an environment / node_modules issue.
