ngModuleType.ngModuleDef.id is undefined - Angular 8 issue when importing NguCarousel module

Question

When I try and import the NguCarousel module, my app breaks because ngModuleType.ngModuleDef is undefined. If I comment out the import of NguCarousel module, the app works fine. I've tried changing versions of the package but no luck. Currently I have v1.5.5 installed with Angular 8.

Any ideas why this module is missing this property?

Answer 1

I ran to the same error today for the same angular version (v8). it was caused by installing higher version of angular material (v12) when I noticed that I forget to specify the version I uninstall it using npm uninstall command then reinstall the correct version. this when the bug occurred for me.

SOLUTION for my problem

1. close the vs code
2. go to project path on file explorer
3. remove node_modules folder
4. open the project on vs code again
5. run command npm i

the node package manager will reinstall all packages with the correct version for you and this should solve the problem.
