Angular build with Warning: export 'ɵa24' was not found in '@angular/material/tabs'

[gopumon]

I recently upgraded my project to Angular 6 and Angular Material 6 (v6.0.2 to be precise) following the instructions at update.angular.io. After upgrade, on ng serve it compiles with some warnings as below.

WARNING in ./node_modules/@angular/material/esm5/material.es5.js

I am using only SnackBar and Dialog components. Any feedback on this are much appreciated.

I have the same error, you find any solution ??

[CaselIT]

I've the same problem. But it appears to be working even with the warning

[crh225]

I just upgraded angular and material to latest and it went away

[CaselIT]

I've updated to version 6.1.0 and I no longer have the warnings, so whatever it was it seems to be fixed

[gopumon]

Yes the warnings disappeared after updating to 6.1.0

[ashishjain16]

I have updated material to v6.2.0 but still warnings shown on production build.any help?

[ashishjain16]

Once all my project dependencies been updated to RxJS 6, I removed rxjs- compat and after that all warnings disappeared. Also on production build i was facing error "TypeError: t is not a function" that also gone after it.

[mxchange]

I'm on 6.2.1 and the warnings show

[ardatan]

Same warnings shown with the latest version of @ngtools/webpack and @angular/material.

[gopumon]

@mxchange , @ardatan Did you try updating the dependencies like @ashishkrjain did?

[ardatan]

@gopumon All dependencies including rxjs are up-to-date.

[gopumon]

@ardatan I am not getting the warnings with angular 6.0.4 and angular material 6.2.1.

You may try the below :

Remove deprecated RxJS 6 features using rxjs-tslint auto update rules.

For most applications this will mean running the following two commands:

yarn global add rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json

(you may use npm with -g flag for installing rxjs-tslint)

Once you and all of your dependencies have updated to RxJS 6, remove rxjs-compat.
