Encountering trouble with Angular material library following upgrade to Angular 6

Upon attempting to compile the application, I encountered the following error:

ERROR in src/app/app.module.ts(15,5): error TS2304: Cannot find name 'MatToolbarModule'. src/app/app.module.ts(16,5): error TS2304: Cannot find name 'MatSidenavModule'. src/app/app.module.ts(17,5): error TS2304: Cannot find name 'MatButtonModule'. src/app/app.module.ts(18,5): error TS2304: Cannot find name 'MatIconModule'. src/app/app.module.ts(19,5): error TS2304: Cannot find name 'MatListModule'. src/app/app.module.ts(20,5): error TS2304: Cannot find name 'MatMenuModule'. src/app/app.module.ts(21,5): error TS2304: Cannot find name 'AuthModule'. src/app/app.module.ts(22,5): error TS2304: Cannot find name 'AppRoutingModule'. src/app/app.module.ts(24,5): error TS2304: Cannot find name 'MatGridListModule'. src/app/app.module.ts(25,5): error TS2304: Cannot find name 'FlexLayoutModule'.

When trying to incorporate Angular Material into the project using ng add @angular/material, I encountered the following message:

Package "@angular/material" was detected but does not support schematics.

Has anyone discovered a solution to this issue?

Answer №1

When upgrading to Angular 6, I smoothly integrated Material 6.0 into my projects. An important step was updating both the local and global Angular CLI. Following the addition of the Material package with ng add @angular/material, be sure to run npm install once more for a seamless experience.

Answer №2

Once you have updated your Angular CLI version,

execute the given command to remove the @angular/material package

npm uninstall @angular/material

Then proceed to run the following command

ng add @angular/material

By doing this, you will effectively resolve the problem at hand.

Answer №3

The package "@angular/material" has been located, but unfortunately does not support schematics.

Essentially, this means that Angular Material is not compatible with ng add at the moment. You will need to wait for a newer version that includes schematics support.

If you are using an older version, you can update Angular Material by running the command: ng update @angular/material with the latest CLI. Alternatively, you can refer to the official instructions for guidance: 

npm install --save @angular/material @angular/cdk

Answer №4

Upon reinstallation of the material, a fresh error popped up. Thankfully, I stumbled upon the solution on this page: Angular 2 agm error. Turns out, it was a compatibility issue with the map wrapper.
