angular: Error: node_modules/ngx-bootstrap/modal/bs-modal.service.d.ts:7:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

 

>PROBLEM

Angular compilation throws the following error:

Error: node_modules/ngx-bootstrap/modal/bs-modal.service.d.ts:7:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

This likely means that the library (ngx-bootstrap/modal) which declares BsModalService has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
