There was a problem with the module '@angular/material' as it was unable to export a certain member

In creating a custom Angular Material module, I have created a material.module.ts file and imported various Angular Material UI components as shown below:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import {
   MatButtonModule,
   MatToolbarModule,
   MatIconModule,
   MatBadgeModule,
   MatSidenavModule,
   MatListModule,
   MatGridListModule,
   MatFormFieldModule,
   MatInputModule,
   MatSelectModule,
   MatRadioModule,
   MatDatepickerModule,
   MatNativeDateModule,
   MatChipsModule,
   MatTooltipModule,
   MatTableModule,
   MatPaginatorModule
} from '@angular/material';

@NgModule({
   imports: [
      CommonModule,
      MatButtonModule,
      MatToolbarModule,
      MatIconModule,
      MatSidenavModule,
      MatBadgeModule,
      MatListModule,
      MatGridListModule,
      MatFormFieldModule,
      MatInputModule,
      MatSelectModule,
      MatRadioModule,
      MatDatepickerModule,
      MatNativeDateModule,
      MatChipsModule,
      MatTooltipModule,
      MatTableModule,
      MatPaginatorModule
   ],
   exports: [
      MatButtonModule,
      MatToolbarModule,
      MatIconModule,
      MatSidenavModule,
      MatBadgeModule,
      MatListModule,
      MatGridListModule,
      MatInputModule,
      MatFormFieldModule,
      MatSelectModule,
      MatRadioModule,
      MatDatepickerModule,
      MatChipsModule,
      MatTooltipModule,
      MatTableModule,
      MatPaginatorModule
   ],
   providers: [
      MatDatepickerModule,
   ]
})

export class AngularMaterialModule { }

I then imported the AngularMaterialModule into the app.module.ts file but encountered the following error:

Module '"@angular/material"' has no exported member "...."

Answer №1

If you've recently updated your angular and/or angular material versions, you may have noticed a change in the imports. With the upgrade to angular material 9, they switched from @angular/material notation to a more specific @angular/material/button like notation.

Instead of importing directly from @angular/material, it's now recommended to import deeply from the specific component, such as @angular/material/button. The good news is that ng update will handle this transition for you automatically.

For more detailed instructions on upgrading, you can refer to the guide at the following link: https://update.angular.io/?v=8.0-9.0

Answer №2

Starting from Angular Material version 9, it is recommended to import each module from a separate path, for example:

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

If you have upgraded your Angular application using ng update (it is advisable to update Angular using this command, but not recommended to skip multiple major versions, check here for more information), the migration process will automatically handle these imports, so no additional actions are required.

Answer №3

If you've recently updated your Angular and/or Angular Material versions, you may have noticed some changes. With the upgrade to Angular Material 9, the way we import material modules in our .ts files has been altered. In the past, we would individually import specific material modules like MatButtonModule, MatToolbarModule, MatIconModule, etc. in a structure like this:

import { MatButtonModule, MatToolbarModule, MatIconModule, MatSidenavModule } from '@angular/material';

However, with the latest updates, we now import these modules through a specific module to prevent loading of the entire material module, which can impact performance and bundle size. Instead, we now import a specific module like this:

import { MatToolbarModule } from '@angular/material/toolbar';

Answer №4

To resolve the issue, consider including the following code snippet 

import {MatToolbarModule} from '@angular/material/toolbar';
inside the file app.module.ts.

Answer №5

When trying to implement a stepper from Angular Material, I encountered a similar error to yours. After some investigation, I realized that the issue was with my code in app.module.js where I had forgotten to include "/stepper" while importing { MatStepperModule } from '@angular/material/stepper';. This resulted in an error being displayed.
